This is the beginning of work to support compressed formats natively in PulseAudio. This adds a pa_stream_new_extended() that takes a format structure, sends it to the server (=> protocol extension) and has the server negotiate with the appropropriate sink to figure out what format it should use. This is work in progress, and works only with PCM streams. Actual compressed format support in some sink needs to be implemented, and extensive testing is required. More details on how this is supposed to work is available at: http://pulseaudio.org/wiki/PassthroughSupport
