Message:

Re #1219:

• Initial version of H264 implementation (codec & packetization).
• Added vid_codec_util.h/c for video codec utilities (e.g: fmtp parser).
• Updated video RTP packetizations to be configurable and have internal state (to be more resilient to packet lost, etc).
• Fixed wrong SPF calculation in PJMEDIA_SPF2.
• Updated vid_codec_test.c to also have RTP packetization test.
• Updated sdp_neg.c to verify H.264 capability match.
