This capability tracks whether "usb-host" device has "hostdevice"
attribute. This attribute allows us to specify full path to the
USB device ("/dev/bus/usb/$bus/$dev") but more importantly, since
QEMU uses qemu_open() for this attribute it allows us to pass
pre-opened FD and have QEMU not bother with opening the file at
all.
The attribute was added in v5.1.0-rc0~71^2~1 QEMU commit.

This caps flag is set when the qemu binary supports the option
"hotplug" for pcie-root-port, ioh3420 (Intel pcie-root-port) and
xio3130-downstream (Intel pcie-downstream-port). If it's available,
it's possible to disable hotplugging/unplugging devices on a
particular port by adding ",hotplug=off" to the qemu device
commandline. This option first appears in qemu-5.0.0.

Almost all TCG query-machines replies match KVM. The only exceptions are
4.2.0 replies on s390x which differ in the reported default CPU type.

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.

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.

For versions where we can probe that the arguments are optional we can
perform the probing by a schema query rather than sending a separate
command to do so.

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.
