Re #1186:

• Added custom negotiation callback mechanism in SDP negotiator, mainly for specific formats that require SDP fmtp negotiation.
• Modified video codec ID string to use encoding name+payload type (was encoding name+clock rate), also added encoding description in video codec info, so duplicated codecs (e.g: multiple H264 configurations) can be differentiated.
• Few enhancements for H264 in ffmpeg wrapper (e.g: added proper profile-id & packetization-mode setup).
