* commit 'b2c087871dafc7d030b2d48457ddff597dfd4925':
  Move x86util.asm from libavcodec/ to libavutil/.
  Move x86inc.asm to libavutil/.
  APIchanges: note error_recognition in lavf
  lavf: add support for error_recognition, use it in avidec, and bump minor API version
  avconv: change semantics of -map
  avconv: get rid of new* options.
  cmdutils: allow precisely specifying a stream for AVOptions.
  configure: add missing CFLAGS to fix building on the HURD
  libx264: Include hint for possible values for configuring libx264
  cmdutils: allow ':'-separated modifiers in option names.
  avconv: make -map_metadata work consistently with the other options
  avconv: remove deprecated options.
  avconv: make -map_chapters accept only the input file index.
  Make a copy of ffmpeg under a new name -- avconv.
  ffmpeg: add a warning stating that the program is deprecated.
  Add weighted motion compensation for RV40 B-frames
  RV3/4: calculate B-frame motion weights once per frame
  Move RV3/4-specific DSP functions into their own context
  mjpeg: propagate decode errors from ff_mjpeg_decode_sos and ff_mjpeg_decode_dqt
  h264: notice memory allocation failure
