9bc3d3355f avcodec/huffman: replace qsort with AV_QSORT 
ff_huff_build_tree uses qsort underneath. AV_QSORT is substantially
faster due to the inlining of the comparison callback. Furthermore, this
code is reasonably performance critical, since in e.g the fraps codec,
ff_huff_build_tree is called on every frame. This routine is also called
in vp6 on every frame in some circumstances.

Sample benchmark (x86-64, Haswell, GNU/Linux), vp6 from FATE:
vp6 (old):
  78930 decicycles in qsort,       1 runs,      0 skips
  45330 decicycles in qsort,       2 runs,      0 skips

   9938 decicycles in qsort,    2048 runs,      0 skips
   8043 decicycles in qsort,    4095 runs,      1 skips

vp6 (new):

7ebe12fc55 mmaldec: Add mpeg2 decoding support 
Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

a17a766190 lavc: Add data and linesize to AVSubtitleRect 
Use the new fields directly instead of the ones from AVPicture.
This removes a layer of indirection which serves no pratical purpose
whatsoever, and will help in removing AVPicture structure completely
later.

Every subtitle encoder/decoder seamlessly points to the new arrays,
so it is possible to deprecate AVSubtitleRect.pict.
