Merge remote-tracking branch 'qatar/master'

* qatar/master:
  vble: remove vble_error_close
  VBLE Decoder
  tta: use an integer instead of a pointer to iterate output samples
  shorten: do not modify samples pointer when interleaving
  mpc7: only support stereo input.
  dpcm: do not try to decode empty packets
  dpcm: remove unneeded buf_size==0 check.
  twinvq: add SSE/AVX optimized sum/difference stereo interleaving
  vqf/twinvq: pass vqf COMM chunk info in extradata
  vqf: do not set bits_per_coded_sample for TwinVQ.
  twinvq: check for allocation failure in init_mdct_win()
  swscale: add padding to conversion buffer.
  rtpdec: Simplify finalize_packet
  http: Handle proxy authentication
  http: Print an error message for Authorization Required, too
  AVOptions: don't return an invalid option when option list is empty
  AIFF: add 'twos' FourCC for the mux/demuxer (big endian PCM audio)
