  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().

  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
