x86Compute() is a static function called only by virCPUx86Compare()
which passes NULL to the 'guest' parameter of x86Compute().
The last caller of x86Compute() that used it with 'guest' != NULL
was an API called 'cpuGuestData'. This API was dropped by commit
03fa904c0c a few years ago. Since then all callers of x86Compute()
uses it with 'guest' = NULL.
Removing the 'guest' parameter allow us to remove a good chunk of
logic that isn't being used for awhile.

There is no guarantee that QEMU and libvirt have been configured
with the same prefix.
In particular, Homebrew on macOS will pass a different, private
prefix for each package version and then use symlinks to make
the files for a specific version appear in the usual locations.
This works perfectly fine as long as one package doesn't try to
go poking around another package's data - which is exactly what
libvirt needs to do in order to read and parse the QEMU interop
data.
qemu_datadir can now be explicitly provided to make this and
other uncommon scenarios work. The common scenario, where QEMU
and libvirt both use the same prefix, is unaffected.

Commit 65b0b746b5 changed spice tests to use latest caps. Before this
change, "FLAG_REAL_CAPS" wasn't being set in testQemuInfoInitArgs(). The
absence of this flag triggered the code path inside
testCompareXMLToArgv() that executed testUpdateQEMUCaps(). This function
will update the host CPU via virQEMUCapsUpdateHostCPUModel() into
virQEMUCapsInitHostCPUModel(). In this function,
virQEMUCapsInitCPUModel() would end up updating the hostCPU inside the
qemuCaps (via virQEMUCapsProbeHostCPU()). Before the forementioned
commit, the host CPU was being defaulted to x86_64, vendor Intel, for
the 'graphics-spice-timeout' test that is using the 'pc' machine type
and 'accel=kvm'.
Today, "FLAG_REAL_CAPS" is being set because we're using the latest caps
from x86_64. This means that the whole code path mentioned above is
skipped. qemuCaps are now being loaded via virQEMUCapsLoadCache()
directly. Without the handling being done by testUpdateQEMUCaps(), the
host CPU is being retrieved later on, down below
qemuProcessCreatePretendCmdPrepare() into qemuProcessUpdateGuestCPU().
The latter will attempt to update the domain cpu and executing a
virCPUCompare with the hostCPU and def->cpu.
All this logic ended up causing a failure of the
'graphics-spice-timeout' test in ppc64 and s390x hosts. This test is
being run with KVM acceleration, and the KVM driver for ppc64 and s390x
will return a default x86_64 CPU with vendor "AMD", making
virCPUCompare() fail with the following message:
"QEMU XML-2-ARGV graphics-spice-timeout.x86_64-latest ... libvirt: CPU
Driver error : the CPU is incompatible with host CPU: host CPU vendor does
not match required CPU vendor Intel"
Fix this test by setting cpu check='none' and avoid the virCPUCompare()
that causes the problem for ppc64 and s390x hosts.
Note that this is a build fix. A more adequate fix would be to mock the
getHost() interface of the cpuDriverX86 for non-x86 hosts, allowing
'fullCPU' to be retrieved in qemuProcessUpdateGuestCPU(), and a proper
x86 CPU to be retrieved in the scenario described above.

The upcoming QEMU 6.2.0 implements a new event called
DEVICE_UNPLUG_GUEST_ERROR, a new event that reports generic device
unplug errors that were detected by the guest and reported back to QEMU.
This new event is going to be specially useful for pseries guests that
uses newer kernels (must have kernel commit 29c9a2699e71), which is the
case for Fedora 34 at this moment. These guests have the capability of
reporting CPU removal errors back to QEMU which, starting in 6.2.0, will
emit the DEVICE_UNPLUG_GUEST_ERROR event. Libvirt can use this event to
abort the device removal immediately instead of waiting for 'setvcpus'
timeout.
QEMU 6.2.0 is also going to emit DEVICE_UNPLUG_GUEST_ERROR for memory
hotunplug errors, both in pseries and ACPI guests. QEMU 6.1.0 reports
memory removal errors using the MEM_UNPLUG_ERROR event, which is going to
be deprecated by DEVICE_UNPLUG_GUEST_ERROR in 6.2.0. Given that
Libvirt wasn't handling the MEM_UNPLUG_ERROR event we don't need to
worry about it - adding support to DEVICE_UNPLUG_GUEST_ERROR will be
enough to cover all future cases.
This patch adds support to DEVICE_UNPLUG_GUEST_ERROR by adding the
minimal wiring required for Libvirt to be aware of it. The monitor
callback for this event will abort the pending removal operation of the
device reported by the "device" property of the event. Most of the heavy
lifting is already done by existing code that handles
QEMU_DOMAIN_UNPLUGGING_DEVICE_STATUS_GUEST_REJECTED, making our life
easier to abort the pending removal operation.

In a few cases we call a public API, wrapped in an if() statement
with both branches written out explicitly. The error branch jumps
onto cleanup label, while the successful prints out a message.
Right after these ifs there's 'ret = true;' and the cleanup
label. The code is a bit more readable if only the error branch
is kept and printing happens at the same level as setting the ret
variable.

Currently, the dommigrate example returns 0 or 1 for success or
failure state, respectively. Except for a few cases where it
forgot to change the @ret variable just before jumping onto the
'cleanup' label. Making the code follow our usual pattern
(initialize @ret to an error value and set it to success value
only at the end) fixes those cases. Also, using EXIT_SUCCESS and
EXIT_FAILURE is more portable (even though on my system they are
just an alias to values the example already uses).
