Merge remote-tracking branch 'qatar/master'

* qatar/master:
  libschroedinger: Switch to function names more in line with Libav style.
  Move code shared between libdirac and libschroedinger to libschroedinger.
  lavfi: uninline avfilter_copy_buffer_ref_props().
  lavf: add missing '*' in a doxy.
  h264: Remove a commented-out function pointer typedef.
  txd: Remove write-only variable in txd_decode_frame().
  mmvideo.c: Remove unused variable in mm_decode_pal().
  build: cosmetics: Add missing end-of-line backslashes to item lists.
  build: cosmetics: Split HEADERS/OBJS/PROGS lists into one entry per line.
  libschroedinger: Move a function to avoid a forward declaration.
  pthread: warn on high thread counts
  vf_yadif: fix missing error handling for avfilter_poll_frame()
  avprobe: allow showing only one container/stream property.
  lavfi: support audio in avfilter_copy_frame_props().
  lavfi: avfilter_merge_formats: handle case where inputs are same
  lavc: add sample rate and channel layout to AVFrame.
  zerocodec: check if the previous frame is missing
  doc: clarify check for NULL pointer style
