Merge remote-tracking branch 'qatar/master'

* qatar/master:
  mov: Use defines for sample flags in fragments
  mov: Use defines for trun flags
  mov: Use defines for tfhd flags
  proresenc: force bitrate not to exceed given limit
  vc1parse: call vc1_init_common().
  wma: don't return 0 on invalid packets.
  asf: prevent packet_size_left from going negative if hdrlen > pktlen.
  mjpegb: don't return 0 at the end of frame decoding.
  rtpdec: Identify incorrectly signalled H263
  vp8dsp: split long line.
  aiff: don't skip block_align==0 check on COMM-after-SSND files.
  dpcm: ignore extra unpaired bytes in stereo streams.
  mp3on4: require a minimum framesize.
  mpc7: assign an error level + context to av_log() msg.
  huffyuv: error out on bit overrun.
  dct-test: Add the missing ff_ prefix to the altivec functions
  dct-test: Remove a stray declaration of a nonexistent function
  movenc: Write the unknown duration as 64 bit fields in ismv
  movenc: Write track durations with all bits set if duration is unknown
