  avs: call release_buffer() at the end.
  Add minor bumps and APIchanges entries for lavc/lavfi changes.
  mpegvideo.c: K&R formatting and cosmetics.
  avconv: avoid memcpy in vsrc_buffer when possible.
  avconv: implement get_buffer()/release_buffer().
  lavfi: add a new function av_buffersrc_buffer().
  lavfi: add avfilter_copy_frame_props()
  lavc: add format field to AVFrame
  lavc: add width and height fields to AVFrame
  lavc: add a sample_aspect_ratio field to AVFrame
  doxy: add website-alike style to the html output
