Some instances of ARCH_IS_PPC64 did not use them.

This function was introduced in commit 41f5c2ca as a way
to probe the same property for multiple devices at once.

Although the resulting representation is very compact, it
doesn't provide any extra features compared to the existing
virQEMUCapsProcessStringFlags() mechanism, which is already
used for pretty much all device properties.

Drop the custom function and datatypes and start using the
standard ones instead.

Note that, in theory, the end result is not identical
because we're no longer probing properties for

  virtio-serial-pci
  virtio-9p-pci
  virtio-rng-pci
  virtio-input-host-pci
  virtio-keyboard-pci
  virtio-mouse-pci
  virtio-tablet-pci

However, chances of any of those devices being compiled
into a QEMU binary where

  virtio-balloon-pci
  virtio-blk-pci
  virtio-scsi-pci
  virtio-net-pci
  virtio-gpu-pci

are compiled out are slim enough that it doesn't make any
difference in practice, as the lack of test suite churn
shows.

In some cases, we are probing multiple devices for the same
property and setting the corresponding capability if it's
found on any of the devices: when that happens, we can quit
early after finding the first property and avoiding a bunch
of string comparisons.

Commit 4ae59411 introduced the ability to make probing for
device properties conditional on a capability being set, but
didn't extend the use of this feature to existing devices.

This commit does the last bit of work, which results in a lot
of pointless QMP chatter no longer happening and our test suite
shrinking a fair bit.

If the user tries to define a domain that has

and also some USB devices, we report an error:
  error: internal error: No free USB ports

Which is technically still correct for a domain with no USB ports.

Change it to:

When trying to destroy a domain (e.g. because we've seen EOF on
the monitor) we try to acquire QEMU_JOB_DESTROY. However, if
max_queued is set in qemu.conf this may fail and since our code
doesn't count on that we will still report domain as active even
though the qemu process is long gone. More specifically, if we've
seen EOF on the monitor, qemuProcessHandleMonitorEOF() is called
which sends MONITOR_EOF job to the event worker pool and
unregisters monitor from the event loop. The worker pool calls
processMonitorEOFEvent() which tries to set job which may fail
due to the limit as described above.

When migrating a domain, qemuMigrationDstPrepareAny() is called
which eventually calls qemuProcessLaunch(conn = NULL, flags =
VIR_QEMU_PROCESS_START_AUTODESTROY); But the very first thing
that qemuProcessLaunch does is check if AUTODESTROY flag is set
and @conn is not NULL. Well, it is.
