Until we clean up and remove all capabilities which no longer make sense
to have separately, we should use virQEMUCapsInitQMPBasicArch to set the
defaults as it's used by qemuxml2argvtest when testing with fake
capabilities.
This allows us to prevent testing dead code paths with the fake
capability tests.

Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable
- VNC - set to "none", unless passthrough of host env variable is set
- SPICE - always set to "spice"
- SDL - always passthrough host env
- No graphics - set to "none", unless passthrough of host env variable is set
The setting of the QEMU_AUDIO_DRV env variable is done in the code which
configures graphics.
If no <audio> element is present, we now auto-populate <audio> elements
to reflect this historical default config. This avoids need to set audio
env when processing graphics.

Historically the virtio-blk frontend by default enabled SCSI emulation
and tried to do SCSI command passthrough. As this was enabled by default
there's a fallback mechanism in place in cases when the backend doesn't
support SCSI for any reason.
This is not the case when disk type=lun is used with 'scsi-block' via
'virtio-scsi'.
We did not restrict configurations when the user picks 'qcow2' or any
other format as format of the disk, in which case the emulation is
disabled as such configuration doesn't make sense.
This patch unifies the approach so that 'raw' is required both when used
via 'virtio-blk' and 'virtio-scsi' so that the user is presented with
the expected configuration. Note that use of <disk type='lun'> is
already very restrictive as it requires a block device or iSCSI storage.
Additionally the scsi emulation is now deprecated by qemu with
virtio-blk as it conflicts with virtio-1 and the alternative is to use
'virtio-scsi' which performs better and is along for a very long time.

None of the tests depend on anything that the machine type would
influence. This will allow us to drop the very old machine type from the
non-real-data tests. If something depends on the machine type it should
be tested with real data rather than this hack.

There's no reason for the files to have qemuxml2xmlout- prefix
since they all live under qemuxml2xmloutdata directory.
