We have some early replies that don't quite match with how
QEMU 2.12.0 as released behaves.

This capability can be used to figure out whether the
QEMU binary at hand supports the machine type property
we need in order to enable SMMUv3 IOMMU support.
Unfortunately we can't avoid probing the RISC-V binaries
along with the ARM ones, since both architectures have
their own 'virt' machine type.

Since we know the full list of machine types supported
by the QEMU binary when probing machine type properties,
we can save some work (and eventually test suite churn,
as more architecture-specific machine types need to be
probed) by only probing machines that we know exist.

Now that we have the list of machine types available when
probing machine type properties, we can list properties for
the canonicalized version of the "pseries" machine type
instead of having to go through "spapr-machine", which we
know to be the parent type for all "pseries-*-machine"
types. By doing this, we'll be able to find even properties
that are only available from a certain versioned machine
type forward, and can't thus be obtained when looking at
the parent type only.

We're going to need information about available machine types
when probing machine type properties soon, and that means we
have to change the order we call QMP commands.

Since commit a4cda054e7 we are using 'ide-hd' and 'ide-cd' instead of
'ide-drive'. We also should probe capabilities for 'ide-hd' instead of
'ide-drive'. It is safe to do as 'ide-drive' is the common denominator
of both 'ide-hd' and 'ide-cd' so all the properties were common.
For now the test data are modified by just changing the appropriate type
when probing for caps.

QEMU 3.1 should only expose the property if the host is actually
capable of creating hugetable-backed memfd. However, it may fail
at runtime depending on requested "hugetlbsize".

Previous commits removed all capabilities from per-device property
probing for:
pci-assign
kvm-pci-assign
usb-host
scsi-generic
Remove them from the virQEMUCapsDeviceProps list and get rid of the
redundant device-list-properties QMP calls.
Note that 'pci-assign' was already useless, because the QMP version
of the device is called 'kvm-pci-assign', see libvirt commit 7257480
from 2012.

Use qemuMonitorTestNewFromFileFull which allows to test commands used
along with providing replies. This has two advantages:
1) It's easier to see which command was used when looking at the files
2) We check that the used commands are actually in the correct order

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.
