Michael Niedermayer a369a6b858 Merge remote-tracking branch 'qatar/master'
* qatar/master: (29 commits)
  fate: add golomb-test
  golomb-test: K&R formatting cosmetics
  h264: Split h264-test off into a separate file - golomb-test.c.
  h264-test: cleanup: drop timer invocations, commented out code and other cruft
  h264-test: Remove unused DSP and AVCodec contexts and related init calls.
  adpcm: Add missing stdint.h #include to fix standalone header compilation.
  lavf: add functions for accessing the fourcc<->CodecID mapping tables.
  lavc: set AVCodecContext.codec in avcodec_get_context_defaults3().
  lavc: make avcodec_close() work properly on unopened codecs.
  lavc: add avcodec_is_open().
  lavf: rename AVInputFormat.value to raw_codec_id.
  lavf: remove the pointless value field from flv and iv8
  lavc/lavf: remove unnecessary symbols from the symbol version script.
  lavc: reorder AVCodec fields.
  lavf: reorder AVInput/OutputFormat fields.
  mp3dec: Fix a heap-buffer-overflow
  adpcmenc: remove some unneeded casts
  adpcmenc: use int16_t and uint8_t instead of short and unsigned char.
  adpcmenc: fix adpcm_ms extradata allocation
  adpcmenc: return proper AVERROR codes instead of -1
