* qatar/master: (58 commits)
  amrnbdec: check frame size before decoding.
  cscd: use negative error values to indicate decode_init() failures.
  h264: prevent overreads in intra PCM decoding.
  FATE: do not decode audio in the nuv test.
  dxa: set audio stream time base using the sample rate
  psx-str: do not allow seeking by bytes
  asfdec: Do not set AVCodecContext.frame_size
  vqf: set packet parameters after av_new_packet()
  mpegaudiodec: use DSPUtil.butterflies_float().
  FATE: add mp3 test for sample that exhibited false overreads
  fate: add cdxl test for bit line plane arrangement
  vmnc: return error on decode_init() failure.
  libvorbis: add/update error messages
  libvorbis: use AVFifoBuffer for output packet buffer
  libvorbis: remove unneeded e_o_s check
  libvorbis: check return values for functions that can return errors
  libvorbis: use float input instead of s16
  libvorbis: do not flush libvorbis analysis if dsp state was not initialized
  libvorbis: use VBR by default, with default quality of 3
  libvorbis: fix use of minrate/maxrate AVOptions
