* 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
