- Defines stereo codec case, similar to RTX, that adds stereo codec to the SDP negotiation. The underlying codec's payload type is similarly defined by "apt". - If this negotiation is successful, codec name is included in sdp line via "acn". - Adds codec setting initializers for these specific stereo cases. - Introduces new Stereo*Factory classes as optional convenience wrappers that inserts stereo codec to the existing set of supported codecs on demand. This CL is the step 5 for adding alpha channel support over the wire in webrtc.
