* qatar/master:
  lavc: add opt_find to AVCodecContext class.
  h264: Complexify frame num gap shortening code
  intreadwrite.h: fix AV_RL32/AV_RB32 signedness.
  Fix decoding of mpegts streams with h264 video that does *NOT* have b frames
  Add minor bumps and APIChanges entries for lavf private options.
  ffmpeg: deprecate -vc and -tvstd
  ffmpeg: use new avformat_open_* API.
  ffserver: use new avformat_open_* API.
  ffprobe: use new avformat_open_* API.
  ffplay: use new avformat_open_* API.
  cmdutils: add opt_default2().
  dict: add AV_DICT_APPEND flag.
  lavf: add avformat_write_header() as a replacement for av_write_header().
  Deprecate av_open_input_* and remove their uses.
  lavf: add avformat_open_input() as a replacement for av_open_input_*
  AVOptions: add av_opt_find() as a replacement for av_find_opt.
  AVOptions: add av_opt_set_dict() mapping a dictionary struct to a context.
  ffmpeg: don't abuse a global for passing frame size from input to output
  ffmpeg: don't abuse a global for passing pixel format from input to output
  ffmpeg: initialise encoders earlier.
