usb: add audio device model
This brings a usb audio device to qemu. Output only, fixed at
16bit stereo @ 480000 Hz. Based on a patch from
H. Peter Anvin <hpa@linux.intel.com>
Usage: add '-device usb-audio' to your qemu command line.
Works sorta ok on a idle machine. Known issues:
* Is *very* sensitive to latencies.
* Burns quite some CPU due to usb polling.
In short: It brings the qemu usb emulation to its limits. Enjoy!
