e6e26a899d tests: unify qemu binary paths for all qemu related tests
Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.

Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

396ca36cb0 qemu: Enforce ACPI, UEFI requirements
Depending on the architecture, requirements for ACPI and UEFI can
be different; more specifically, while on x86 UEFI requires ACPI,
on aarch64 it's the other way around.

Enforce these requirements when validating the domain, and make
the error message more accurate by mentioning that they're not
necessarily applicable to all architectures.

Several aarch64 test cases had to be tweaked because they would
have failed the validation step otherwise.

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.

QEMU allows for TSC frequency to be explicitly set to enable migration

Libvirt already supports setting the TSC frequency in the XML using

    </clock>

which will be transformed into

    -cpu Model,tsc-frequency=1234567890

84cc51ea74 cputest: Add tests for virCPUUpdateLive API
The test takes

  x86-cpuid-Something-guest.xml CPU (the CPU libvirt would use for
    host-model on a CPU described by x86_64-cpuid-Something.xml without
    talking to QEMU about what it supports on the host)

and updates it according to CPUID data from QEMU:

  x86_64-cpuid-Something-enabled.xml (reported as "feature-words"
    property of the CPU device)

and

  x86_64-cpuid-Something-disabled.xml (reported as "filtered-features"
    property of the CPU device).

The result is compared to

  x86_64-cpuid-Something-json.xml (the CPU libvirt would use as
    host-model based on the reply from query-cpu-model-expansion).

The comparison is a bit tricky because the *-json.xml CPU contains fewer
disabled features. Only the features which are included in the base CPU
model, but listed as disabled in *.json will be disabled in *-json.xml.
The CPU computed by virCPUUpdateLive from the test data will list all
features present in the host's CPUID data and not enabled in *.json as
disabled. The cpuTestUpdateLiveCompare function checks that the computed
and expected sets of enabled features match.

- x86-cpuid-Something-enabled.xml will contain CPUID bits present in
    x86-cpuid-Something.json (i.e., enabled by QEMU for the "host" CPU)

- x86-cpuid-Something-disabled.xml will contain all CPUID bits from
    x86-cpuid-Something.xml which are not present in
    x86-cpuid-Something.json (i.e., CPUID bits which the host CPU
    supports, but QEMU does not enable them for the "host" CPU)
