[PATCH v4 00/13] Cleanup deprecated audio features, take 2

[Paolo Bonzini <pbonzini@redhat.com>]

In this version the QEMU_AUDIO_* options go away, but it is still
possible to pick a default audio backend from the list provided to
--audio-drv-list.  The code is still simplified a lot compared to
having all the legacy parsing code and the -audio-help function.
I had to keep QEMU_AUDIO_DRV=none because it is used by libqtest;
a possibility for the future could be to add a "-audio none" option
without a model.  For now I kept this setting as it is a subset of the
previous accepted values, and it can be deprecated separately.

At the end of this series, all devices can be configured with
-audiodev.  Therefore, I decided to forbid mixing the default
audio backend with audiodevs or with -nodefaults.

Patches 1-2 are Martin's patches that didn't end up in the previous
pull request.

Patches 3-4 change audio.c to use Error ** a bit more.

Patches 5-7 introduce the minimal code to create a default audio
backend.

Patches 8-11 introduce a machine property "audiodev" and plumb
it into all machines with an embedded sound card.

Patch 12 cleans up error propagation up to the realize functions
of the devices, so that error messages are nicer when patch 13
forbids usage of default audio backends with -nodefaults.

v3->v4: for now, always allow default audiodev backend even
        together with -audiodev.  The new plan is to first improve
        -audio so that it can create a default audiodev backend,
        and only then remove the possibility to use the first
        -audiodev as the default audiodev backend.

        do not use error_report+abort
