123880d333 qemu: Add AAVMF32 to the list of known UEFIs
Add a path for UEFI VMs for AArch32 VMs, based on the path Debian is using.
libvirt is the de facto canonical location for defining where distros
should place these firmware images, so let's define this path here to try
and minimize distro fragmentation.

385c1cc96c qemu: Check non-migratable host CPU features
CPU features which change their value from disabled to enabled between
two calls to query-cpu-model-expansion (the first with no extra
properties set and the second with 'migratable' property set to false)
can be marked as enabled and non-migratable in qemuMonitorCPUModelInfo.

Since the code consuming qemuMonitorCPUModelInfo currently ignores the
migratable flag, this change is effectively changing the CPU model
advertised in domain capabilities to contain all features (even those
which block migration). And this matches what we do for QEMU older than
2.9.0, when we detect all CPUID bits ourselves without asking QEMU.

As a result of this change

    <cpu mode='host-model'>
      <feature name='invtsc' policy='require'/>
    </cpu>

will work with all QEMU versions. Such CPU definition would be forbidden
with QEMU >= 2.9.0 without this patch.

bb3363c90b qemu: Use full CPU model expansion on x86
The static CPU model expansion is designed to return only canonical
names of all CPU properties. To maintain backwards compatibility libvirt
is stuck with different spelling of some of the features, but we need to
use the full expansion to get the additional spellings. In addition to
returning all spelling variants for all properties the full expansion
will contain properties which are not guaranteed to be migration
compatible. Thus, we need to combine both expansions. First we need to
call the static expansion to limit the result to migratable properties.
Then we can use the result of the static expansion as an input to the
full expansion to get both canonical names and their aliases.

f013828992 qemu: Get host CPU model from QEMU on x86_64
Until now host-model CPU mode tried to enable all CPU features supported
by the host CPU even if QEMU/KVM did not support them. This caused a
number of issues and made host-model quite unreliable. Asking QEMU for
the CPU it can provide and the current host makes host-model much more
robust.

This commit fixes the following bugs:

    https://bugzilla.redhat.com/show_bug.cgi?id=1018251
    https://bugzilla.redhat.com/show_bug.cgi?id=1371617
    https://bugzilla.redhat.com/show_bug.cgi?id=1372581
    https://bugzilla.redhat.com/show_bug.cgi?id=1404627
    https://bugzilla.redhat.com/show_bug.cgi?id=870071

In addition to that, the following bug should be mostly limited to cases
when an unsupported feature is explicitly requested:
