Implemented with base64-encoded strings in qga json protocol.
Glib portable GIOChannel is used for data I/O.

Optinal stdin parameter of guest-exec command is now used as
stdin content for spawned subprocess.

If capture-output bool flag is specified, guest-exec redirects out/err
file descriptiors internally to pipes and collects subprocess
output.

Guest-exe-status is modified to return this collected data to requestor
in base64 encoding.

Child process is spawn asynchronously and exit status can later
be picked up by guest-exec-status command.

stdin/stdout/stderr of the child now is redirected to /dev/null

Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.

Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:

  make qemu-ga.exe

or:

  make msi

To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.

To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.

An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.

To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.

ARM/AArch64 KVM guests don't have any way to identify
themselves as KVM guests (x86 guests use a CPUID leaf). Now, we
could discuss all sorts of reasons why guests shouldn't need to
know that, but then there's always some case where it'd be
nice... Anyway, now that we have SMBIOS tables in ARM guests,
it's easy for the guest to know that it's a QEMU instance. This
patch takes that one step further, also identifying KVM, when
appropriate. Again, we could debate why generally nothing
should care whether it's of type QEMU or QEMU/KVM, but again,
sometimes it's nice to know...

If any store instruction writes the code inside the same TB
after this store insn, the execution of the TB must be stopped
to execute new code correctly.
As described in ARMv8 manual D3.4.6 self-modifying code must do an
IC invalidation to be valid, and an ISB after it. So it's enough to end
the TB after ISB instruction on the code translation.
Also this TB break is necessary to take any pending interrupts immediately
after an ISB (as required by ARMv8 ARM D1.14.4).

A future patch will move some error checking from the parser
to the various QAPISchema*.check() methods, which run only
after parsing completes.  It will thus be possible to create
a python instance representing an implicit QAPI type that
parses fine but will fail validation during check().  Since
all errors have to have an associated 'info' location, we
need a location to be associated with those implicit types.
The intuitive info to use is the location of the enclosing
entity that caused the creation of the implicit type.

Note that we do not anticipate builtin types being used in
an error message (as they are not part of the user's QAPI
input, the user can't cause a semantic error in their
behavior), so we exempt those types from requiring info, by
setting a flag to track the completion of _def_predefineds(),
and tracking that flag in _def_entity().

No change to the generated code.
