We can do the trivial replacement of QEMU_AUDIO_DRV with -audiodev
without much difficulty - just a matter of tweaking the CLI generator
and tests.

The full support with XML configurability doesn't need to block us
dropping use of QEMU_AUDIO_DRV.

Libvirt lacks proper support for the existing multi-seat features in
QEMU. This audio stuff might be a good motivation to finally implement
the full multi-seat feature set.
