7c8bf09edd swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2
pshuf+paddd is slightly faster than phaddd.
The real gain is in pre-ssse3 processors like AMD K8 and K10, which get
a big boost in performance compared to the mmxext version

  rtmp: Add message tracking
  rtsp: Support mpegts in raw udp packets
  rtsp: Support receiving plain data over UDP without any RTP encapsulation
  rtpdec: Remove an unused include
  rtpenc: Remove an av_abort() that depends on user-supplied data
