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!
