Replace the custom audio logging infrastructure (dolog macro and
AUD_log/AUD_vlog) with standard QEMU error reporting (error_report,
error_printf, error_vprintf).
Note that we also dropped the abort() call in DEBUG_AUDIO, as it is not
usually compiled with, doesn't help much, and can easily be added back
when doing development as needed.
