* commit '7ab551f9':
  h264: prevent theoretical infinite loop in SEI parsing

Conflicts:
	libavcodec/h264_sei.c

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

Conflicts:

	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

Merged-by: Michael Niedermayer <michaelni@gmx.at>

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

The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.

This is how all the other init functions operate.

This allows running all the tests individually and/or in parallel.
