* qatar/master:
  resample: allocate a large enough output buffer
  fate: fix enc_dec_pcm tests with remote target
  wmaenc: remove bit-exact hack
  FATE: remove WMA acodec tests
  FATE: add WMAv1 and WMAv2 encode/decode tests with fuzzy comparison
  FATE: add AC-3 and E-AC-3 encode/decode tests with fuzzy comparison
  qtrle: Use bytestream2 functions to prevent buffer overreads.
  vqavideo: check malloc return values
  x11grab: fix a memory leak exposed by valgrind
  threads: fix old frames returned after avcodec_flush_buffers()
  MPV: always mark dummy frames as reference
  h264: fix deadlocks on incomplete reference frame decoding.
  mpeg4: report frame decoding completion at ff_MPV_frame_end().
  mimic: don't use self as reference, and report completion at end of decode().
