core: Add extended stream API to support compressed formats

Browse source 
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
