Michael Niedermayer 9f088a1ed4 Merge remote-tracking branch 'qatar/master'
* qatar/master:
  mpegvideo: reduce excessive inlining of mpeg_motion()
  mpegvideo: convert mpegvideo_common.h to a .c file
  build: factor out mpegvideo.o dependencies to CONFIG_MPEGVIDEO
  Move MASK_ABS macro to libavcodec/mathops.h
  x86: move MANGLE() and related macros to libavutil/x86/asm.h
  x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h
  aacdec: Don't fall back to the old output configuration when no old configuration is present.
  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
  vsrc_movie: discourage its use with avconv.
  avconv: allow no input files.
  avconv: prevent invalid reads in transcode_init()
  avconv: rename OutputStream.is_past_recording_time to finished.
