RTSP bug 831645 / Bechen

RTSP bug 831645
- waiting for review
bug 877116 - [RTSP] audio playback latency is serious with the following media streams(Video:H.264 Audio:AAC)
- According to rfc3640, we can divide a RTP packet into several Access-Unit, and calculate the timestamp for each AU.
  - It works now, but since we divide a RTP packet into several small pieces, also increase the ipc loading. And we observe the smallest aac AU is only 9 bytes (silence aac frame), means that a RTP packet will be divided into more than 100 AUs corresponding to 100 ipc, 100 slots. Then we must adjust the slot buffer number in RTSPTrackBuffer bug 877193.

The b2g process crash on our ipc call "onMediaDataAvailable", seems we can't do ipc on android thread. Help by / Cervantes.
