Attachment: WIP AudioPolicyManager

I've been poking at a simple webapi to do audio policy management. This WIP doesn't quite work yet, and will require additional code in gaia.

Port switching seems to work now. Need to check the port enumeration and add checking of the current port.

I've fleshed out the implementation. We'll need an audiopolicy counterpart in gaia.

I wonder if we need to expose the concept of different cards. We just assume card 0 here, but that probably won't hold up when we want to start handling bluetooth through here.

The interface seems reasonable to me. Also this idea is under discussing on w3c, they want to define the input/output device sleection, BTW, I have a question, for mobile device, some input/output device has the pair problem, should we throw exception if UA assign the HW don't support the kind of combination? Especially for the voice call case.

For the Bluetooth/UsbAudio case, I think the pluseaudio is a good start on TV system, it's routing policy is simple and usually don't contain the phone call case.

Throwing an exception is fine, though I don't know how the audio policy code would recover from it. Maybe we just need to list all valid combos.
