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.

Avoid calling the command and fix test fallout.

e67b6dcf36 qemu: capabilities: Probe caps for 'ide-hd' instead of 'ide-drive'
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.

4168e33755 qemu: remove leftover property probing
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.

22d8f55b21 qemu: capabilities: Detect active block commit via QMP schema probing if possible

perform the probing by a schema query rather than sending a separate
