[Qemu-devel] [PATCH 00/25] audio: -audiodev option, multiple options

[Kővágó, Zoltán]

This patch series adds support to multiple audio backends.  The first
part of the series (until -audiodev command line option) was submitted
multiple times, see
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg05037.html
and
http://lists.nongnu.org/archive/html/qemu-devel/2015-07/msg00920.html

Afterwards I add support to multiple backends.  Audio fronteds gain a
new audiodev option to specify the id of the audiodev to use.  The
audiodev= option is required, unless you use the old environment
variable based configuration, in that case it must not used (and you
can't use multiple backends).

Finally I also make mixeng usage optional, it can save us some useless
format converting when not needed.  Also makes easier to support formats
currently not supported by qemu (as only the backend has to support it,
not the mixeng).

For easier testing pull https://github.com/DirtYiCE/qemu.git tag 
audio-multi-v1.

Please review.
