2999bd7da2 x86: xvid_idct: port SSE2 iDCT to yasm
The main difference consists in renaming properly labels, and
letting yasm select the gprs for skipping 1D transforms.

84d173d3de xvididct: Ensure that the scantable permutation is always set correctly
This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

  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

a786c8259d idct: Split off Xvid IDCT
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.
