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.

Now that we no longer care about any of their properties, there's no need
to call `device-list-properties` on these devices.

dcfbfffd6a tests: Fix qemu replies wrt usb-host properties
My commit of v6.9.0-rc1~457 was a bit too harsh. While it served
its purpose (adding usb-host.hostdevice capability) it has a side
effect: because I copied reply from qemu-5.1.0 to older .replies
files one might now think that say qemu-3.1.0 supports both
.guest-reset and .guest-resets-all properties. But in fact it
doesn't. There are three problematic properties:

1) guest-reset, introduced in v4.0.0-rc0~56^2
2) guest-resets-all introduced in v4.2.0-rc1~9^2
3) suppress-remote-wake introduced in v5.0.0-rc0~148^2~4

Remove these properties from versions that could not have had
them.

b560d1c876 qemu_capabilities: detect if confidential-guest-support is available
virQEMUCapsProbeQMPMachineProps currently skips any not supported
machine type which includes `none` as well.

In order to start probing that machine type we need to add an exception
to not skip it when probing QEMU capabilities.

fb292c659f qemu: capabilities: Probe QMP schema before probing commands
All supported QEMU versions now support query-qmp-schema. In the future
it will be possible to use the output of query-qmp-schema to also detect
commands reliably.

Since we are at the point where we have the least amount of .replies
files needing changing for a long time, move the 'query-qmp-schema' bits
before 'query-commands' to prepare for the future.

66c5674e79 qemu_capabilities: Add QEMU_CAPS_USB_HOST_HOSTDEVICE
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.

cbd4ab4cc6 qemu: new capabilities flag pcie-root-port.hotplug
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.
