* qatar/master: (33 commits)
  rtpdec_qdm2: Don't try to parse data packet if no configuration is received
  ac3enc: put the counting of stereo rematrixing bits in the same place to make the code easier to understand.
  ac3enc: clean up count_frame_bits() and count_frame_bits_fixed()
  mpegvideo: make FF_DEBUG_DCT_COEFF output coeffs via av_log() instead of just via AVFrame.
  srtdec: make sure we don't write past the end of buffer
  wmaenc: improve channel count and bitrate error handling in encode_init()
  matroskaenc: make sure we don't produce invalid file with no codec ID
  matroskadec: check that pointers were initialized before accessing them
  lavf: fix function name in compute_pkt_fields2 av_dlog message
  lavf: fix av_find_best_stream when providing a wanted stream.
  lavf: fix av_find_best_stream when decoder_ret is given and using a related stream.
  ffmpeg: factorize quality calculation
  tiff: add support for SamplesPerPixel tag in tiff_decode_tag()
  tiff: Prefer enum TiffCompr over int for TiffContext.compr.
  mov: Support edit list atom version 1.
  configure: Enable libpostproc automatically if GPL code is enabled.
  Cosmetics: fix prototypes in oggdec
  oggdec: fix memleak with continuous streams.
  matroskaenc: add missing new line in av_log() call
  dnxhdenc: add AVClass in private context.
  ...

swscale changes largely rewritten by me or replaced by baptsites due to lots of bugs in ronalds code.
Above code is also just in case its not obvios to a large extended duplicates that where cherry picked
from ffmpeg.

c8f487deae swscale: fix YUV420P 9/10bit support.
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

05238927b7 fate: make lavfi tests output only md5
Instead of saving huge raw files, use the md5: output pseudo-protocol
to calculate the checksum of the file directly.  This is especially
useful when testing on remote targets as it avoids transferring 3.6GB
over the network.

213a4cbb39 Add lavfi-pixfmts LE tests.
The corresponding lavfi-pixfmts BE tests are not yet added, as there
are some bugs in the scaler (scaling rgba, argb, bgra, abgr, yuva420p)
which result in differences with the LE reference, and I cannot
visually check the generated files on BE.
