Merge remote-tracking branch 'qatar/master'

* qatar/master:
  vorbis: Validate that the floor 1 X values contain no duplicates.
  avprobe: Identify codec probe failures rather than calling them unsupported codecs.
  avformat: Probe codecs at score 0 on buffer exhaustion conditions.
  avformat: Factorize codec probing.
  Indeo Audio decoder
  imc: make IMDCT support stereo output
  imc: move channel-specific data into separate context
  lavfi: remove request/poll and drawing functions from public API on next bump
  lavfi: make avfilter_insert_pad and pals private on next bump.
  lavfi: make formats API private on next bump.
  avplay: use buffersrc instead of custom input filter.
  avtools: move buffer management code from avconv to cmdutils.
  avconv: don't use InputStream in the buffer management code.
  avconv: fix exiting when max frames is reached.
  mpc8: fix maximum bands handling
  aacdec: Turn PS off when switching to stereo and turn it to implicit when switching to mono.
