VirtioSound

Summary: Implement device emulation for the new virtio-sound device.

A specification for a virtio sound device is being worked on. The specs are pretty close to be finalized and a Linux guest driver should be available soon.

Project goal is a virtio sound device implementation for QEMU. The device will use QEMU's audio subsystem to play back and capture audio samples.
