Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

Build of QEMU with dtrace fails on macOS:

  LINK    x86_64-softmmu/qemu-system-x86_64
error: probe colo_compare_miscompare doesn't exist
error: Could not register probes
ld: error creating dtrace DOF section for architecture x86_64

The reason of the error is explained by Adam Leventhal [1]:

  Note that is-enabled probes don't have the stability magic so I'm not
  sure how things would work if only is-enabled probes were used.

net/colo code uses is-enabled probes to determine if other probes should
be used but colo_compare_miscompare itself is not used explicitly.
Linker doesn't include the symbol and build fails.

The issue can be resolved if is-enabled probe matches the actual trace
point that is used inside the test. Packet dump toggle is replaced with
a compile-time conditional definition.

dtrace USDT is fully supported since OS X 10.6. There are a few
peculiarities compared to other dtrace flavors.

1. It doesn't accept empty files.
2. It doesn't recognize bool type but accepts C99 _Bool.
3. It converts int8_t * in probe points to char * in
   header files and introduces [-Wpointer-sign] warning.

ppc patch queue 2020-09-08

This supersedes ppc-for-5.2-20200904, it fixes a couple of bugs in
that PR and adds a few extra patches.

Next pull request for qemu-5.2.  The biggest thing here is the
generalization of ARM's start-powered-off machine property to all
targets.  This can fix a number of odd little edge cases where KVM
could run vcpus before they were properly initialized.  This does
include changes to a number of files that aren't normally in my
purview.  There are suitable Acked-by lines and Peter requested this
come in via my tree, since the most pressing requirement for it is in
pseries machines with the POWER secure virtual machine facility.

In addition we have:
 * Daniel Barboza's rework and clean up of pseries machine NUMA handling
 * Correction to behaviour of the nvdimm= generic machine property on
   pseries
 * An optimization to the allocation of XIVE interrupts on KVM
 * Some fixes for confused behaviour with kernel_irqchip when both
   XICS and XIVE are in play
 * Add HIOMAP comamnd to pnv flash
 * Properly advertise the fact that spapr_vscsi doesn't handle
   hotplugged disks
 * Some assorted minor enhancements

Ever since commit 537fe2d there
has been a 'linkage' to sdl for compiling baum.c. Originally it
had to do with including sdl cflags for any file including sdl
headers. There is no longer any such need for baum.c, but the
association has persisted in the make system, and with the switch
to meson it has now become a hard requirement, which now causes
chardev-baum.so to not be produced if sdl is not configured.
Remove this bogus linkage.

All Meson executables should specify their dependencies explicitly, either
directly or indirectly via declare_dependency.  Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.
LIBS is not used at all, so drop that one as well.

In a few cases the dependencies were not yet specified, so add them.

The glib compilation flags were added to QEMU_CFLAGS.  While we still
want them to be added to all compilation commands (at least for now),
do that via GLIB_CFLAGS rather than via QEMU_CFLAGS.  This shows that
glib is a special case and makes it clearer that QEMU_CFLAGS is only
