1092a88e13 qemu: capabilities: Introduce QEMU_CAPS_QCOW2_DISCARD_NO_UNREF
The qcow2 driver allows passing discards to the storage while keeping
the reference of the block, and just marking it as zeroed. This can
decrease the levels of fragmentation of the qcow2 metadata when
discards are enabled.

111cfc5532 qemu: capabilities: Fix testing of 'TCG' capabilities probing
The logic in 'virQEMUCapsInitQMP' invokes a second probe of qemu in case
when acceleration is used and TCG is supported to specifically probe the
CPU and features of non-accelerated guests.

The same logic must then be used in 'qemucapabilitiestest' when
replaying the data for testing otherwise the test would fail.

Export 'virQEMUCapsHaveAccel' for test usage and use the same logic
in 'testQemuCaps'.

Fix the comment in 'virQEMUCapsInitQMP' to outline what's happening.

903ea9370d qemu_capabilities: Report Hyper-V Enlightenments in domcapabilities
Inside of qemuCaps (for the corresponding accelerator) we have
full host CPU expansion stored, among with supported Hyper-V
Enlightenments. To report them in the domain capabilities, we
just have to pick those starting with "hv-" and see if we know
them.

You may notice that neither of our domaincapsdata test shows any
enlightenment. This is because the test works by parsing
corresponding qemucapabilitiesdata/caps_*.xml file and none of
these store the full host CPU expansion (hostCPU.fullQEMU)
because that is runtime piece of information and not formatted
into virQEMUCaps XML.

10f4784864 qemu_capabilities: Query for Hyper-V Enlightenments
Now that we have qemuMonitorGetCPUModelExpansion() aware of
Hyper-V Enlightenments, we can start querying it. Two conditions
need to be met:

  1) KVM is in use,
  2) Arch is either x86 or arm.

It may look like modifying the first call to
qemuMonitorGetCPUModelExpansion() inside of
virQEMUCapsProbeQMPHostCPU() would be sufficient but it is not.
We really need to ask QEMU for full expansion and the first call
does not guarantee that.

For the test data, I've just copied whatever
'query-cpu-model-expansion' returned earlier, therefore there are
no hv-* props. But that's okay - the full expansion is not stored
in cache (and thus not formatted in
tests/qemucapabilitiesdata/caps_*.replies files either). This is
purely runtime thing.
