dde77d1cf6 qemu: capabilities: Don't probe device properties for 'virtio-*-s390' devices
The devices no longer exist in qemu since the 2.6 release. Drop the
probing of the device properties and fix the data for
qemucapabilitiestest.

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.

aa21615ccb tests: qemucapabilitiesdata: Fix formatting of manually added hunk
Commit 66c5674e79 added a query for the device properties of 'usb-host'
but the command header isn't formated the same way as if it were
autogenerated. Reformat all the files.

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.

4.2.0 replies on s390x which differ in the reported default CPU type.

35e4c15326 tests: Refresh capabilities for QEMU on ppc64
Now that we're probing machine type properties using the
latest machine type rather than the "spapr-machine" parent,
we can finally discover properties that are not available
on all machine types.

This commit refreshes replies for QEMU 4.0.0 as well as
3.1.0 to show not only that we're actually discovering new
machine type properties this way, but also that the number
of available machine type properties increases with each
subsequent QEMU release.

If qom-list-properties had been available in QEMU 2.10.0,
we could now drop the explicit version number checks for
the QEMU_CAPS_MACHINE_PSERIES_MAX_CPU_COMPAT and
QEMU_CAPS_MACHINE_PSERIES_RESIZE_HPT capabilities, but
unfortunately it wasn't, so we have to keep them around
still.

d22c6221fc qemu: Probe canonicalized machine type
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.
