Change audio/video sync to be based on mapping RTP timestamps to NTP.

Video Engine:
- Instead compensate for video capture delay by modifying RTP timestamps.
- Calculate the relative offset between audio and video by converting
  RTP timestamps to NTP and comparing receive time.

RTP/RTCP module:
- Removes the awkward video modification of NTP to compensate
  for video capture delay.
- Adjust RTCP RTP timestamp generation in rtcp_sender to have the same offset
  as packets being sent from rtp_sender.
