[Qemu-devel] [PATCH v2 0/6] -audiodev option

[Kővágó, Zoltán]

This series of patches adds a new -audiodev command line option to specify audio
subsytem parameters instead of environment variables. This will later allow us
to specify multiple audio backends. The syntax is something like this:
 -audiodev driver_name,property=value,...
like:
 -audiodev alsa,frequency=8000,channels=1

The first commit adds a qapi Audiodev struct that describes the audio backend
options. The next 4 commits are some miscellaneous additions that are needed by
the last commit which finally adds the -audiodev option.

For users with esoteric platforms or needs please check I did not break anything
accidentally. For easier testing, pull https://github.com/DirtYiCE/qemu.git tag
audio-cmdline-v2.

Please review.
