ppc: fft: Build AltiVec optimizations in the standard way
Conflicts:
libavcodec/ppc/Makefile
Merged-by: Michael Niedermayer <michaelni@gmx.at>
DTS primarly needs to be separated from PCM, and PCM can contain cliping and
overshoots at the very start which can mimic DTS headers.
If this isnt sufficient then more of the DTS stream has to be decoded
and analyzed
Fixes ticket3784

h264: prevent theoretical infinite loop in SEI parsing
Conflicts:

Not merged, as this would remove 2 bitstream compliance checks.
The specification does not allow the bitstream to end in the middle
of these variable length elements and we have no samples which
have such non compliant truncation either so its better to error
out. Which is simpler as well
This issue also has been fixed long ago

idct: Split off Xvid IDCT
Conflicts:
libavcodec/Makefile
libavcodec/mpeg4videodec.c
libavcodec/x86/Makefile
libavcodec/x86/idctdsp_init.c
This split is somewhat restructured leaving the xvid IDCT available
outside mpeg4 if manually selected.
The code also could not be merged unchanged as it conflicted with a
bugfix in FFmpeg

The first try failed to work with some build flags
The gcc version affected is very old and unmaintained AFAIK thus i made no
attempt to report this to the gcc developers.
The workaround is pushed as it may still affect users and does affect one
fate client

Properly address CVE-2011-3946 and parse bitstream as described in the spec.
