* Thread safe MPEG4 quantization functions.
Cleaned up version of patch provided by Michael
- fixed compiling problems on gcc
- added const qualifiers every where it was possible to help C compiler
optimization.
- added the mpeg_quant_matrices param to all ASM function prototype
in comments (even if it's not used, that shows we do it deliberatly)
- forces m[intra][0][0] = 8, otherwise XviD could write invalid streams.
* Added real CRC computing in xvid_bench.c

- removed const qualifiers because the functions do not return const matrices
(i'll change that in a later time)

- Hmmm, i've been obliged to revert the previous patch because ofthe mmx code using the same arrays, so they need to be global. We'll have to fix that, because it's not *thread safe*.

ProfDrMorph's new (unoptimized) Luma Masking code:
luminance masking now works with relative values instead of absolute ones
the new code raises/lowers oberall quant for especially bright/dark frames ( Weber-Fechner law: humans see less differences in bright scenes )
every pixel with a very low lumi value is set to 0 for better compressability ( again the Weber-Fechner law; below a certain intesity humans won't see anything )

Big patch, use it with care (tests done with GNU/Linux) :
- Trivial warnings in encoder.c line 282 ret1 = ret 2 = 0;
- Lot of "New line at end of file missing" warnings fixed (gcc3)
- All 2d arrays have been turned into 1d arrays
To force alignment of matrices on stack, use DECLARE_ALIGNED_MATRIX
(read portab.h)
Win32 users should give feedback.
