Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  avcodec_default_reget_buffer(): fix compilation in DEBUG mode
  fate: Overhaul WavPack coverage
  h264: fix mmxext chroma deblock to use correct TC values.
  flvdec: Remove the now redundant check for known broken metadata creator
  flvdec: Validate index entries added from metadata while reading
  rtsp: Handle requests from server to client
  movenc: use timestamps instead of frame_size for samples-per-packet
  movenc: use the first cluster duration as the tfhd default duration
  movenc: factorize calculation of cluster duration into a separate function
  doc/APIchanges: fill in missing dates and hashes.
  lavc: reorder AVCodecContext fields.
  lavc: reorder AVFrame fields.

*
* AVFrame.data[] should be 32- or 16-byte-aligned unless the CPU doesn't

* Decoders request a buffer of a particular size by setting

*
* Decoders cannot use the buffer after returning from
* avcodec_decode_audio4(), so they will not call release_buffer(), as it
* is assumed to be released immediately upon return.
*

* functions to find the required data size and to fill data pointers and
