    [version] Up version to 0.0.1.8
    
    This release introduces initial support for GRUB4DOS
    sector-mapped disks.  Currently, only HDD images with MBRs
    are supported.
    
    Please note that this is an early stage in supporting this
    scenario, so you might find quirks.  Also be aware of the
    limitations:
    - If your booted-from disk image file gets _moved_ while you
      are booted from it, expect terrible things to happen.  Try
      to avoid such things as defragmenting the filesystem with
      the disk image on it!
    - There isn't really a good way to know which Windows disk a
      GRUB4DOS backing disk corresponds to!  Not enough information
      is available to make the right decision.  BIOS drive numbers
      have no relevance in Windows, so we cannot exactly identify
      which backing disk is correct for a disk image
    - WinVBlock is not capable of magic; your booted disk image
      _must_ have drivers and device ID associations so that the
      _real_ disks are found at boot time!

    [filedisk] Add MBR check for GRUB4DOS disks
    
    We lack any good means of finding the correct backing disk for
    a boot-time file-backed disk.  Here is a really cheap check
    which will test for an MBR where we would expect on on the
    backing disk.  This doesn't support CD/DVD, obviously.

    [filedisk] Increase timeout for threaded disk processing
    
    If there's nothing to do but a possible device__free(),
    just sleep for up to a whole second before checking.

    [filedisk] Initial support for booting a filedisk from GRUB4DOS
    
    Whee.  We scan memory for GRUB4DOS sector-mapped disks, create
    filedisks for them, then hook them so that the first time they
    are used, we try to find the appropriate backing disk for each.
    
    The limitations of the current implementation are:
    - We assume the first disk is the right backing disk (very naive)
    - We don't check to make sure we don't open our own disk
    - It's pretty slow for some reason that needs investigation
    - There is not really a good way to associate GRUB4DOS mappings
      to Windows disks; not enough information is passed!
    - If the image file for a filedisk gets moved while we are using
      it, expect terrible things to happen!

    [filedisk] Implement threaded filedisk creation function
    
    filedisk__create_threaded() should return a pointer to a
    threaded, file-backed disk.

    [filedisk] Add support for threaded filedisks
    
    We now have a disk__io routine which enqueues a request for
    later processing.  We implement a device__free routine to
    support such asynchronous filedisks.  We have a thread
    function per threaded filedisk which processes the queue
    of requests.

    [filedisk] Allow for a file offset
    
    It's useful to have a base offset into a file from which
    the virtual disk's sectors will be considered to start.

    [filedisk] Add GRUB4DOS module
    
    Distinguish between the case of GRUB4DOS RAM disks and
    GRUB4DOS sector-mapped (file-backed) disks.  A new probe
    routine is added (which currently does nothing).

    [filedisk] Put in own subdir and change to library
    
    There is a plan to support GRUB4DOS sector-mapped disks,
    so we will need another probe routine, suggesting that
    there should be a GRUB4DOS source file in a filedisk/
    directory, as there is a GRUB4DOS source file in the
    ramdisk/ directory.

    [disk] Allow for asynchronous IRP completion
    
    After much debugging, it was revealed that in order to use
    ZwReadFile() for a file-backed disk during boot, one needs
    to return STATUS_PENDING to the caller and start a worker
    thread who will use ZwReadFile() and then complete the IRP.

    [irp,bus] Send and handle IRP completion properly for detach
    
    The disk detach handler was not completing the IRP and the
    IRP processor was not checking for completion in an outer
    while() loop.  Both fixed.

    [major] Re-work device structures and creation
    
    This rather large commit affects a majority of the AoE and
    WinVBlock modules.  It is unfortunately large in order to
    ensure that after the series of changes were made, that a
    system was still bootable from a WinVBlock disk.
    
    What was involved:
    
    A DEVICE_OBJECT's DeviceExtension member no longer points to
    one of our device types.  All of our device types were
    previously structures which included the structures they
    derived functionality from as their first members.  So you
    had something like a RAM disk with a disk as its first
    member, a disk having a device as its first member.  So to
    access any one of the structures, you could quite simply
    cast a pointer.
    
    Now a DeviceExtension points to a pointer to a device__type.
    A device__type has an ext member which is a pointer to the
    instance of the next-higher structure type, such as a
    disk__type.  A disk__type also has an ext member, so that
    AoE, RAM, and file-backed disks can extend it.
    
    Each device class provides a global creation routine, which
    tracks the device instance in a list of created devices for
    that type.  The device class' creation routine should set
    default parameters.  The creation routine can override the
    device routines used by callers calling the routines of the
    "base class" (the device type).  As an example, when you
    create a RAM disk, you:
      - create a disk
        - which creates a device
        - which hook's a device routine for the device
      - hook some of the disk's routines
      - add the RAM disk to the global list
    
    When deleting the RAM disk, you:
      - call the deletion routine you hooked for the disk
        - which calls the deletion rout. it hooked for the dev.
      - remove the RAM disk from the global list
    
    Some copy'n'pasted comments were corrected.
    
    Some code expecting the base-class-as-first-member-of-
    derived-class was exposed and modified appropriately.
    
    get_ptr() macros were changed.
    
    DEVICE_OBJECT deletion paths were tied to device__free()
    calls.
    
    Some TODOs are left: More error-checking when calling
    module initialization functions, watching NULL pointer
    dereferences when walking sibling pointers.

    [bus] Use new bus creation strategy
    
    When creating the boot bus or when a user manually installs
    a bus device, the bus module will use the new device creation
    scheme.
    
    When the bus module initializes, it creates the boot bus,
    which is a root-enumerated device via IoReportDetectedDevice().
    Using this kernel function means that the PnpManager owns the
    PDO.  If a user manually installs a bus device, PnpManager also
    owns the PDO.  So the create_pdo() routine for a bus doesn't
    make a lot of sense, except for indirectly for the case of the
    boot bus only.
    
    Also, when the IoReportDetectedDevice() is used, we must
    manually call our attach_fdo() function to create the
    DEVICE_OBJECT which we own and which we will associate with
    the driver-internal bus & device details.
    
    There is a really big nasty TODO left over in this commit
    which should be removed as soon as possible.  In shifting to
    the new device classing scheme, we are part-way through,
    where some devices use a DEVICE_OBJECT's DeviceExtension as
    a device__type_ptr, and the bus uses it as a device__type_ptr*.
    So for now, we have the mini IRP handling system sense if it
    should compensate for this.
    
    The next steps will be to move all of the various disk types
    to use counterpart strategies for device classing.  But hey,
    it still boots.

    [device,bus] Further develop device routines
    
    Much of it unused for now, but eventually (seems like it's
    always eventually) each device type will create an instance
    of a type it would like to derive from, then overrides
    whatever operations it wants to.  When the device is asked
    to perform operations, it should either have sensible, do-
    nothing defaults or meaningful device-specific operations.

    [bus] Create boot bus here, introduce init function
    
    The bus module is now responsible for creation of bus PDOs,
    such as the boot bus which exposes WinVBlock-supported boot
    disks.  We now have bus__init() and bus__finalize() funcs
    which are called by the driver module.
    
    We also mimic the device module by having a bus__create()
    function, though it is currently unused, also like the
    device__create() function.

    [device] Don't use a pointer for device operations
    
    Instead of pointing at some device operations structure,
    we actually copy the operations' function pointers for
    each device.

    [device] Introduce device creation routine
    
    Though currently unused, the idea is to eventually have the
    different device type modules as providers of their device
    types.  The new device-common module will produce a device
    structure which has device-common properties.  A caller can
    then override whichever properties they need to, such as the
    device operations.
    
    Also, device creation should track created devices for easy
    tear-down later on.

    [device] Introduce device header and move details there
    
    Move device specifics out of the driver header and into a
    device headers, instead.  We are on our way to a form of
    device functionality inheritance...  Something like:
    
      device
      ..bus
      ..disk
      ....aoe
      ....ramdisk
      ....filedisk

    [winvblock/probe] Move disk probe routine into bus
    
    It makes some sense that we can delay our RAM disk probing
    until the bus is actually queried for children.  This means
    that the DriverEntry() returns sooner.

    [version] Up version to 0.0.1.7
    
    This version sees a couple of changes:
    
    - AoE has been split off as a separate driver that depends
    on the WinVBlock bus driver.  This removes the bus driver's
    dependency on NDIS.SYS.  You can boot from an AoE disk still,
    but pay attention to the service load order; you want NDIS to
    load first, then your NIC's driver, then WinVBlock, then AoE.
    
    - Geometry detection has been added for file-backed disks, so
    you can hopefully do:
    
      winvblk attach c:\foo.hdd h 0 0 0
    
    and get the right geometry.
    
    - We now always create a root-enumerated bus device.  There's
    no longer a need to add the /WINVBLOCK=BUS=1 option to the
    BOOT.INI or TXTSETUP.SIF files.

    [bus/disk,bus/filedisk] Add geometry detection
    
    Now you can specify something like:
    
      winvblk attach c:\foo.hdd h 0 0 0
    
    and geometry detection will be attempted when the first
    sector of the disk is accessed.  We use some of the logic
    from H. Peter Anvin's MEMDISK to look at FAT and MBR
    params.

    The extremely nice work of Bo Brantén found at:
    
    http://www.acc.umu.se/~bosse/
    
    includes HTTPDisk, a read-only HTTP SAN driver, of sorts.
    
    He has very kindly provided permission for its incorporation
    into WinVBlock.  It will be developed to be a "feature
    driver", just as AoE is a "feature driver".
    
    Please note that HTTPDisk is GPLv2 or any later version.

    [project] Split AoE off, part 3
    
    At last, the unfortunately monolithic AoE module can be
    separated from the bus, RAM disk and file-backed disk
    code.  This is the final part of the estimated 3 commits.
    
    Now that AoE is its own driver, but dependent on WinVBlock,
    we have to consider the service load order in a booted-from
    scenario.

    [bus,aoe,irp] AoE mini IRP handling in AoE module
    
    The bus module pretty well needs to expose the bus device to
    other drivers so that they can register their mini IRP
    handling tables with it.  bus__dev() now yields the FDO.
    
    The un-register function was mis-named in the IRP module.
    
    We are now registering the AoE IOCTL handling twice, but
    this is not a big deal.  When AoE is finally split off,
    the bus module will no longer register anything AoE-related.

    [registry,aoe] Move AoE Registry setup into AoE module
    
    AoE needs to register its protocol with NDIS and also does
    some Registry manipulation.  This logic has been moved from
    the Registry module into the AoE module (which is getting
    quite monolithic now).  This is still towards splitting AoE
    into its own driver.

    [irp] Use mini IRP handling chain
    
    When an IRP dispatch comes in, we special-case a power
    IRP, or pass the IRP along to irp__process().
    
    irp__process() will walk each table of IRP handlings
    in the device's chain of registered tables, looking for
    an IRP handling that matches the IRP major and minor
    codes.  This is roughly similar to the PDO stacked
    beneath multiple FDOs approach, but just a little less
    complex and with perhaps less memory and management
    overhead.
    
    A feature (provided by a driver) can register handled
    IRP types on a device, then WinVBlock should use that
    feature's functions to process the IRP.  I hope WinVBlock
    can call functions in another driver in this way. :)
    
    So now when a bus or disk device is created, the default
    driver IRP handling table is registered as well as the
    device-specific handling table (bus or disk).  We used
    to manually build a large table with these tables copied
    into it, but not anymore.

    [irp] Move mini IRP handling into its own module
    
    We introduce bus/irp.c for the miniature IRP handling logic.
    
    We also introduce code for an IRP handling table chain.  The
    goal of such a chain is to allow IRP handlings to be
    dynamically added and removed for a device.  An example use
    would be for the AoE system to register IOCTL handling with
    the WinVBlock bus device, so that the bus processes the
    IOCTLs.  If the AoE system is unloaded, it should be able to
    un-register the handling of these IOCTLs.
    
    Currently, the IRP handling table chain is not used, but
    this will change in a future commit.

    [build] Move majority of code into bus subdir
    
    The plan is to split AoE functionality off into its own driver,
    to avoid WinVBlock's dependency on NDIS for those users who
    do not require or desire the AoE feature.
    
    Similarly, future features with dependencies can have their own
    directories and their own .SYS drivers.
    
    For now, all driver code including AoE has been moved into bus/,
    but AoE will eventually come out of there.
    
    A strategy needs to be determined to allow for the single bus
    device to accept features in a modular fashion, and to route
    applicable feature-wide control signals to each feature's driver.
    
    For example, the WinVBlock bus (an "HDD controller" of sorts) can
    support certain virtual disk types natively.  When an AoE driver
    starts, it could look for the bus and register itself as a
    feature if the bus is found.  Thenceforth, a user-land utility
    could request an AoE-attach of the WinVBlock bus, who could forward
    that request on to the AoE driver.

    [bus] Remove disk details from Bus_AddChild
    
    A fair bit of shuffling.  Devices extensions now have
    a device operations member which is a struct of function
    pointers; one for device creation and one for device
    initialization.  This is akin to the disk operations
    structure found as a member of a disk.
    
    Bus_AddChild() is now simply passed a device extension
    pointer, which points at device extension details to add
    to the bus.  It will call the particular PDO creation
    routine provided by whoever populated the device
    extension.  That routine will return a PDO that will be
    attached to the bus.  Bus_AddChild() is also still
    passed a pointer to the bus device object to which the
    child belongs.
    
    The only PDO creation routine at this time is obviously
    disk__create_pdo(), since we are a virtual SCSI driver!
    The reason for this bit of abstraction is in case anyone
    finds the code handy some day as a reference for the
    bus-and-child model.  This code is not at that stage yet.

    [driver] Introduce device initialization routine
    
    Any device on the bus could have an initialization routine, so
    the device extension now has an init function pointer member.
    
    disk__create_pdo() will setup the device extension for disks
    to redirect to the init function pointer member of the disk's
    operations structure.

    Big oops.  For auto-generation of a bus device, we

    assumed that we already have a PDO, which we don't.

    [driver,bus] Remove re-initialization routine
    
    MAJOR LEARNING: A boot driver re-initialization routine is
    too late to create the bus device and its disks!  Why?
    If the boot volume was not installed during a previous
    session, that means it's a new volume.  Never-before-seen
    volumes are only registered as possible boot volumes at a
    point before boot driver re-initialization routines are
    called.
    
    As such, our previous re-initialization routine was _only_
    useful if the expected boot volume on one of the RAM disks
    was somehow already installed...  It so happens that in
    testing, I often modify the RAM disk image by using it
    with QEmu as the virtual machine's hard disk drive.  Thus,
    the volume gets installed at that time and persists.  The
    Blue Screen of Death that folks were having was pretty
    mysterious.  The symptoms involved the Session Manager
    crashing at a post-0x0000007B time, which was unexpected.
    
    The crash was due to an uninstalled volume being installed
    too late, as mentioned.  So now probe__disks() happens
    at bus creation time, and bus creation time happens either
    during DriverEntry (if the user requests) or when the PnP
    Manager re-establishes a previously installed bus device.
    Both of these times occur before a boot driver
    re-initialization routine occurs.
    
    An easy way to reproduce the issue was to change the MBR
    signature on a disk already installed, thus making it a
    "brand new" disk, with "brand new" volumes on it.
    
    This also explains why the Recovery Console will only boot
    from a WinVBlock RAM disk with the /WINVBLOCK=BUS=1 switch.
    This switch caused early bus creation _and_ early disk
    probing.
    
    EXTRA NOTE: Including the previous commit in CHANGES.log,
    which was missed.

    [filedisk] Initial file-backed disk support
    
    Fairly messy, this commit introduces file-backed disk support.
    
    The aoe.exe user-mode program has been renamed to winvblk.exe.
    It now accepts two new commands:
    
    winvblk attach \??\<path> <type> <cyls> <heads> <sectors>
    winvblk detach <disk num>
    
    <path> is the file path to a disk image.  For now, you should prefix
    "\??\" in front of the path.
    
    <type> is one of 'f', 'c', 'h' for floppy, optical disc, hard disk,
    respectively.
    
    <cyls> is the cylinder count.  Common values might be:
    65535: for an optical disc drive
       80: for a floppy disk
    
    <heads> is the count of heads.  Common values might be:
    255: for an optical disc drive
      2: for a floppy disk
    
    <sectors> is the count of sectors per track, not to be confused
    with the total sector count for the media.  Common values might be:
    15: for an optical disc drive
    18: for a 1.44 MB floppy disk
    36: for a 2.88 MB floppy disk
    
    These geometry parameters are not optional at this time.
    
    <disk num> is the internal disk number.  Unfortunately the only
    way to currently find this out is with 'winvblk show', which yields
    some garbage since it is interpreting all disks as AoE SANs.  This
    is obviously a FIXME item.
    
    GRUB4DOS and MEMDISK modules also got a slight fix to initialize
    disk parameters with all zeroes.
    
    The file-backed disk logic currently leaks HANDLES, since it does
    not close them upon a 'detach'.  This is obviously a FIXME item.
    
    To prevent duplicate PDOs, every file-backed disk has a 32-bit
    "hash" which is really just a very stupid attempt at a unique ID
    based on LBADiskSize and the file path to the disk image.  Heh.
    
    Some examples for attaching file-backed disks:
    
    winvblk attach \??\d:\RamXP.HDD h 52 128 63
    winvblk attach \??\d:\some.iso c 65535 255 15
    winvblk attach \??\d:\floppy144.vfd f 80 2 18

    [filedisk] Introduce skeleton for file-backed disk class
    
    A rip-off of the RAM disk module, minus RAM disk functionality.
    This skeleton will be developed into a file-backed disk class.
    Currently implemented is a probing routine which will create a
    single 10 MB dummy HDD which silently discards writes and reads
    as all zeroes.

    [cosmetics] Run indent twice due to indent bug
    
    You might or might not have noticed that 'indent' will take
    a file and change its mind about how to indent it.  Take that
    resulting file and run 'indent' again and it will put the file
    back the way it was.  Thus there is an "even" format and an
    "odd" format.  This is silly.  As a work-around, the indent.sh
    and indent_add.sh scripts will run 'indent' twice on a file.
    
    Yeesh.

    [major] Turn disk structure inside out
    
    ...Kind of.  There are currently five places where devices are
    created:
    
    1. Bus created in bus.c
    2. AoE disk created in bus_dev_ctl.c
    3. AoE disk created in probe.c
    4. GRUB4DOS disk created in probe.c
    5. MEMDISK created in probe.c
    
    Each of these places is currently responsible for populating the
    details of the device class structures.  They will now inform
    the Bus_AddChild() routine of how much device extension space
    they require.
    
    For example, a RAM disk contains a disk and a disk contains the
    device-common structure.  Thus Bus_AddChild() needs to allocate
    (via IoCreateDevice()) enough device extension space for all of
    this.
    
    Previously, the disk structure contained a union of the different
    disk classes.  I prefer the model where a child class can have
    knowledge of a parent class, but not vice versa.
    
    This change involved a lot of shuffling, as well as the need to
    fix a bug which probably should have been fixed separately;
    see the DeviceTextLocationInformation handling in disk_pnp.c.

    [disk_pnp] Split ID query logic for disk class
    
    The PnP ID query now calls disk__query_id() which in turn
    calls the disk class-specific function to return the right
    ID(s) in the passed wide-char string buffer.
    
    There should no longer be any checks anywhere for the
    IsRamdisk boolean member of the disk structure.  Now we
    are free to remove that member and re-arrange how we use the
    device extension space, rather than having a union for our
    difference disk classes.

    [disk_dev_ctl] Split MaximumTransferLength logic for disk class
    
    The MaximumTransferLength we return for an IOCTL_STORAGE_QUERY_PROPERTY
    is now returned from a disk class-specific function: The max_xfer_len
    function pointer member of the disk type structure.
    
    AoE and RAM disk modules now implement their own max_xfer_len() func.

    [disk] Split disk IO into AoE and RAM disk modules
    
    The disk structure now includes a function pointer member to
    represent the appropriate I/O routine for the different disk
    classes.  These classes are currently AoE and RAM, but could
    include others in the future, such as file-backed disks.
    
    disk__io() is a function which calls the appropriate routine
    for a given disk (via the device extension space for now).
    
    The AoE module no longer has any knowledge of RAM disks.  Yay.

    temporarily merged into disk.h.  These details should be moved
    out at some point, perhaps.

    According to karyonix (developer of FiraDisk), the Windows
    compiler intrinsics __movsd and __movsq are faster than
    RtlCopyMemory() for RAM disk I/O.  We implement fast_copy()
    in aoe.c to accomplish this.
    
    Of course, once AoE and RAM disks have been properly split,
    this should end up with just the RAM disks.

    [driver] OsLoadOptions support needed for Recovery Console
    
    We now make a note of the OsLoadOptions during registry checking
    and implement get_opt() in the driver module for finding a
    specific WinVBlock option.  WinVBlock options should appear in
    BOOT.INI or TXTSETUP.SIF as a switch like this:
    
    /WINVBLOCK=option1=value1,option2=value2
    
    Recovery Console requires our disks to be discovered before the
    driver re-initialization routine.  Using the above feature, we
    will now execute the re-initialization routine early if the user
    requests, since this routine will create a bus object.  The user
    requests this with an OsLoadOption like this:
    
    /WINVBLOCK=BUS=1

    [driver] Use pre-installed bus if possible
    
    To ensure that we function, we've historically forced the creation
    of the bus device.  The documentation suggests that users use the
    Add New Hardware Wizard to add the driver.  This resulted in two bus
    devices: The proper one known as a SCSI adapter, and a boot-up
    unknown device which was annoying.  For PE environments where our
    driver is very simply injected through TXTSETUP.SIF entries, the
    boot-up unknown device bus will still be generated.

    Commit f92581dcd0d3e80f5a4b26959a3a5621d8378c83 should not have
    changed ULONG_PTR to winvblock__uint32_ptr.  ULONG_PTR is not
    an unsigned long *, but an unsigned long which pointers are
    sometimes cast to and from.
    
    ExAllocatePool() is deprecated and so has been wrapped with a
    macro which instead calls ExAllocatePoolWithTag() with the tag
    'klBV' ("VBlk").
    
    NdisQueryBuffer -> NdisQueryBufferSafe
    NdisBufferVirtualAddress -> MmGetSystemAddressForMdlSafe

    [disk] Fix booting Windows 2003 PE .ISO
    
    Several changes made hither and thither to pay closer attention
    to fixed versus removable media responses to queries.  Windows
    Server 2003 appeared to be trying to probe for a FAT filesystem
    on the emulated ODD.  That's fixed now.
    
    Also fixed MEMDISK probing to correctly set the heads, cylinders
    and sectors-per-track.
    
    A lot of the responses we provide to queries could be simpler
    copies of structures built at device creation time.  These could
    go into the device extension space.  Another ToDo.

    [bus] Initial test for mini IRP handling
    
    Implemented handling_table[] in the bus module.  The bus module has
    also been updated to copy this table into a new bus device.
    
    The picture of a bus device's mini IRP handling stack now goes:
    IRP_MJ_PNP && IRP_MN_QUERY_DEVICE_RELATIONS ? bus foo()
    IRP_MJ_PNP && IRP_MN_START_DEVICE ? bus pnp_start_dev()
    IRP_MJ_CREATE ? driver create_close()
    IRP_MJ_CLOSE ? driver create_close()
    driver old_strategy()
    driver all_irps()
    
    Where lower handlings are only pursued if
    the completion boolean is not set.
    
    A simple foo() which catches IRP_MJ_PNP with
    IRP_MN_QUERY_DEVICE_RELATIONS just for testing.
    foo() should be removed soon.
    
    IRP_MJ_PNP, IRP_MN_START_DEVICE moved to pnp_start_dev()

    [driver] First test with new mini IRP handling strategy
    
    The driver IRP dispatch routine now scans through the DeviceObject's
    DeviceExtension's irp_handler_stack(_ptr) looking for IRP major and
    minor function matches.  An appropriate handler function is called,
    if available.
    
    The IRP_MJ_CREATE and IRP_MJ_CLOSE have their own create_close()
    IRP handler function now, for example.
    
    Now each of the case labels in the IRP function-handling switch
    statements in all modules can be re-worked to use this system.
    This means less indentation!
    
    Also of note is a change to the bus module to copy the default
    mini-stack of IRP handlings from the driver module to any new device.

    [irp,driver] Add mini IRP handling stacks
    
    An irp__handling structure esentially matches an irp__handler
    function to the IRP major and minor functions it is intended to
    handle.  Booleans are used for the case where such a handler handles
    multiple major and/or minor combinations.
    
    In order to facilitate knowledge of when an Irp has been fully
    handled for the driver module, we implement a boolean completion
    status parameter.  If an irp__handler wants to prevent the Irp
    from further processing by the driver Irp dispatch routine, it
    should set the completion status to TRUE.
    
    This miniature IRP handling strategy is sitting doing nothing until
    routines are ported to use it.

    [driver] Remove bus and disk details from the device extension
    
    The eventual goal is for each module to know what it needs to know
    and to delegate module-specific tasks to the appropriate modules.
    
    In working towards this goal, the device extension in driver.h no
    longer contains space for bus or disk structures.  This involved
    major access changes.  Where modules used to access the bus/disk
    members of the device extension, they now use helper functions to
    get a pointer to these structures.
    
    The helper functions get_bus_ptr() and get_disk_ptr() are in the bus
    module.  This isn't really right, since the bus module should
    eventually know nothing about disks.  It's a temporary measure.
    
    The bus module has always been responsible for adding child devices
    as well as the bus device itself.  When adding a device, the bus
    module now allocates enough device extension space to include the
    driver-common structure as well as the appropriate bus- or disk-
    specific structure.
    
    It might be good if other modules inform
    the bus module of how much device extension space they need in the
    future.  This commit does not introduce such logic, but it's an
    idea for later.

    before they include driver.h, since driver.h needs to know the size
    of disk__type.

    [irp] Introduce IRP header
    
    Moved some IRP specifics out of driver.h.
    
    We have an unfortunate circular dependency where several modules
    need to know the driver__dev_ext structure from driver.h, but that
    structure also includes structures from irp.h, bus.h, disk.h.  These
    things need to be shuffled around some more until they're prettier.

    [bus,driver,probe] Re-work probe invocation and bus FDO creation
    
    Probe routines had a bus FDO parameters.  We only allow for one such
    global FDO, so this was silly.  The global bus FDO is renamed from
    Bus_Globals_Self to bus__fdo.  Probe routines simply use it.
    
    The driver code was calling each of the probe routines by name.  Now
    we call a single routine probe__disks() which itself can call each
    probe routine by name.
    
    The bus FDO creation has been modified to work directly with the
    bus__fdo global instead of the previous middle-man behaviour.
    Hopefully this does not lead to any race conditions.

    Michael Brown's registry manipulation functions in his "sanbootconf"

    to registry.c.  After upping the version and releasing, changes to
    registry.c will continue.

    Probing code no longer attempts to map the physical memory for the

    Instead, each I/O request will map memory, and only for the size of

    [abstraction] Rework IRP handlers, move boot-disk probing code
    
    - Changed my mind about IRP handlers; we use an IRPHandler function
      type now
    - We used to probe for a MEMDISK and/or an AoE target (via aBFT)
      in the bus code; we call these functions in probe.c from
      DriverEntry() now
    - driver.c handles device creation and closing now, and passes on
      any other IRPs to the device's particular Dispatch() function.
      Currently, there is only a Bus and Disk device type, where Disk
      should really be abstracted some more to split AoE from MEMDISK
    
    All of the 'include's are looking really messy right now, but we
    _should_ be on our way to being cleaner, where modules should not
    need to know so much about other modules.

    [feature] MEMDISK support
    
    The code is extremely hacky, but MEMDISKs can be discovered and used
    at boot time now.  We check the old real-mode INT 0x13 hook, follow some
    bread crumbs to find MEMDISK 3.82, then note the MEMDISK's geometry and
    details.
    
    We hack AoERequest() to simply copy memory for the MEMDISK case.
    
    Neither the wacky globals/statics, nor the MEMDISK installation check,
    nor the AoE I/O hijacking check are really the right strategy, but reworking
    WinAoE has been slow going thus far.  The ToDos are becoming more obvious.
    
    It would likely be best to implement classes for an AoE disk and a MEMDISK,
    and to split out (abstract) knowledge of AoE specifics from things like
    the bus and disk code.  This will take time, but would allow for other
    classes to eventually be implemented...  Things like:
    
    Software RAID
    File-backed disks
    User-mode back-ends
    HTTPDisk (already exists, but reworked to sit on our bus)
    
    Also, regardless of the disk's interface, we should support floppy, HDD,
    and ODD (optical disc drive) emulation.

    [debug] Improve DBG() macro
    
    DBG() is a hook which calls xDbgPrint() and then DbgPrint().  The macro
    uses the ternary operator to accomplish the hook, and produces a code
    path which can never yield false.  The compiler should optimize the
    resulting code, thus saving any additional cost in space.  The hook is
    thus accomplished for free.  It's a hook in the sense that args from DBG()
    are passed through to DbgPrint(), but not before we inject another
    function call with unrelated and position-dependent args.

    [disk] FIXME: Hack to allow compilation with WinDDK 6001.18001
    
    _EIGHT_BYTE and _READ_CAPACITY_DATA_EX are already available in the
    WinDDK 6001.18001 Windows 2000 build environment. This is not likely a
    permanent solution.

    Debugging messages in aoe.c now clearly indicate which file and function they
    belong to.
