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.

e41e3b29be qemu: Probe machine types for both KVM and TCG
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.

4586b11bed tests: qemucaps: Update 4.1.0 capabilities to a more recent version
Update the capabilities from a non-upstream version (9c70209b63 is not
in qemu.git) to qemu upstream commit 33d6099906 (2019/06/18) so that we
get the QMP schema 'features' field support and are able to detect that
the 'file' block backend supports dynamic auto-read-only.

Note that I've rebuilt this on a machine with a more modern kernel and
microcode which exposes e.g. the recent CPU bug mitigations, thus I
opted to keep the CPU changes rather than trying to do a franken-caps
by updating only the output of query-qmp-schema.

a3f2c802d2 qemu: Don't use full CPU model expansion
We used type=full expansion on the result of previous type=static
expansion to get all possible spellings of CPU features. Since we can
now translate the QEMU's canonical names to our names, we can drop this
magic and do only type=static CPU model expansion.
