Re #1182:

• Added video stream interface in vid_stream.h, the video stream will be able to handle different video formats in encoding and decoding direction.
• Renamed video device stream class identifiers from 'pjmedia_vid_stream*' to 'pjmedia_vid_dev_stream*' as 'pjmedia_vid_stream' is used by video stream interface.
• Added ffmpeg video capability to be able to parse SDP format param for H263 and also decide video format for encoding direction based on remote preference and local format-capability setting.
• Added some new APIs in jitter buffer for handling video stream: pjmedia_jbuf_put_frame3(), pjmedia_jbuf_get_frame3(), pjmedia_jbuf_peek_frame(), and pjmedia_jbuf_remove_frame().
• Moved pjmedia_stream_info_from_sdp() from session to stream
