Michael Niedermayer 715c8a5a50 Merge remote-tracking branch 'qatar/master'
* qatar/master: (28 commits)
  dfa: use more meaningful return codes
  eatgv: check vector_bits
  eatgv: check motion vectors
  Mark a number of variables only used in av_dlog() calls as av_unused.
  dvdec: drop const qualifier from variable to eliminate a warning
  avcodec: Improve comment for thread_safe_callbacks to avoid misinterpretation.
  tests/utils: don't ignore the return value of fwrite()
  lavfi/formats: use sizeof(var) instead of sizeof(type).
  lavfi: remove avfilter_default_config_input_link() declaration
  lavfi: always enable the scale filter and depend on sws.
  vf_split: support user-specifiable number of outputs.
  avconv: remove stray useless comment.
  mpegmux: add stuffing to avoid incomplete PCM frames
  rtsp: avoid const warnings from strtol() call
  avserver: check return value of ftruncate()
  lagarith: make offset array type unsigned
  dfa: add some checks to ensure that decoder won't write past frame end
  aacps: NEON optimisations
  aacps: align some arrays
  aacps: move some loops to function pointers
  ...
