a30dac15dc qemu_capabilities: Detect memory-backend-*.prealloc-threads property
The prealloc-threads is property of memory-backend class which is
parent to the other three classes memory-backend-{ram,file,memfd}.
Therefore the property is present for all, or none if QEMU is
older than v5.0.0-rc0~75^2~1^2~3 which introduced the property.

Anyway, the .reserve property is the same story, and we chose
memory-backend-file to detect it, so stick with our earlier
decision and use the same backend to detect this new property.

da20199762 qemu: capabilities: Assume QEMU_CAPS_AES_KEY_WRAP and QEMU_CAPS_DEA_KEY_WRAP for s390 only
qemu introduced these options in 2eb1cd0768 ("s390x: CPACF: Handle key
wrap machine options") released in qemu-v2.3.0 but was exposed in
query-command-line-options only in 5bcfa0c543 ("util/qemu-config: fix
missing machine command line options").

The problem is that they are exposed even for architectures which don't
actually in fact support those.

Make the two capabilities a bit more useful by assuming them only on
s390 and thus removing them from other arches.

8dac0ca1b2 qemu: implement setting of rotation rate for SCSI/IDE disks
This is available in QEMU with "ide-hd" and "scsi-hd" device
types. It was originally mistakenly added to the "scsi-block"
device type too, but later removed. This doesn't affect libvirt
since we restrict usage to device=disk.

When this property is not set then QEMU's default behaviour
is to not report any rotation rate information, which
causes most guest OS to assume rotational storage.

e07994aade qemu: probe for -vnc audiodev property
The -audiodev arg is a new way to configure audio devices in QEMU to
replace the QEMU_AUDIO_DRV env variable. This arg is not visible in
the "query-command-line-options" output since it is entirely QAPI
driven, not QemuOpts. It also isn't in "query-qmp-schema" though
since there's no QMP command that uses the Audiodev type yet.

So probe for the existance of this feature by looking for the
-vnc "audiodev" property. This won't let us determine which
precise audio backends QEMU has been built with, but for now
that's no worse than with env variables today.
