7dd5b0c54b tests: qemucapabilities: Drop mostly duplicated data
When GIC support was introduced (QEMU 2.6 timeframe) we needed
to make sure both GICv2 hardware and GICv3 hardware were handled
correctly, and that was achieved by having separate capabilities
data for each.

Now that we have capabilities data for several QEMU versions we
can stop storing data for GICv2 and GICv3 hardware separately,
and instead have GICv2 data for QEMU <= 2.10 and GICv3 data for
QEMU >= 2.12, without losing any coverage.

61ea70341a tests: Rename ppc64le caps to ppc64
The architecture itself is called ppc64, and it can run both in big
endian and little endian mode - the latter is known as ppc64le.

From the (virtual) hardware point of view, ppc64 is a more accurate
name so it should be used here.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken

0861080f0e conf: Add usability blockers to virDomainCapsCPUModel
When a hypervisor marks a CPU model as unusable on the current host, it
may also give us a list of features which prevent the model from being
usable. Storing this list in virDomainCapsCPUModel will help the CPU
driver with creating a host-model CPU configuration.

* Extract filling bhyve capabilities from virBhyveDomainCapsBuild()

   easier by not having to mock firmware directory listing and
   hypervisor capabilities probing
 * Also, just presence of the firmware files is not sufficient
   to enable os.loader.supported, hypervisor should support UEFI
   boot too
 * Add tests to domaincapstest for the main caps possible flows:
    - when UEFI bootrom is supported
    - when video (fbus) is supported
    - neither of above is supported

e958fb5b15 qemu: Report better host-model CPUs in domain caps
One of the main reasons for introducing host-model CPU definition in a
domain capabilities XML was the inability to express disabled features
in a host capabilities XML. That is, when a host CPU is, e.g., Haswell
without x2apic support, host capabilities XML will have to report it as
Westmere + a bunch of additional features., but we really want to use
Haswell - x2apic when creating a host-model CPU.

Unfortunately, I somehow forgot to do the last step and the code would
just copy the CPU definition found in the host capabilities XML. This
changed recently for new QEMU versions which allow us to query host CPU,
but any slightly older QEMU will not benefit from any change I did. This
patch makes sure the right CPU model is filled in the domain
capabilities even with old QEMU.

The issue was reported in
https://bugzilla.redhat.com/show_bug.cgi?id=1426456

614581f32b Introduce domain_capabilities
This new module holds and formats capabilities for emulator. If you
are about to create a new domain, you may want to know what is the
host or hypervisor capable of. To make sure we don't regress on the
XML, the formatting is not something left for each driver to
implement, rather there's general format function.

The domain capabilities is a lockable object (even though the locking
is not necessary yet) which uses reference counter.
