When sending v1 of the "Support machine-default audiodev" series,
Zoltan suggested keeping the default audio backends, so I am sending a
reduced version of the pull request.
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.
Patches 12-13 forbid some not-so-sensible usage of default
audio backends.
