b52fcba9cd Fix decoding ATI VCR2 codec, sample in 
samples/V-codecs/ATI-VCR12/ATI/VCR2test.avi
Software decoding was broken since r8865, when two new context variables
were added, but not initialized in vcr2_init_sequence().
Another such context variable was added in r18381.

996b099a0f Branchless setting of MB_TYPE_8x8DCT. 
Not benchmarked as i failed to find a sample that uses this one. But it should be faster.

d9ef0d2e14 Mark index as unsigend so gcc knows it doesnt need a sign extension on x86_64. 
Any tips on how i can convince gcc that it doesnt need a
mov     %eax, %eax
in every get_bits() ?

0b882b4009 Fix crash in MLP decoder due to integer overflow. 
Probably only DoS, init_get_bits sets buffer to NULL, thus causing a
NULL-dereference directly after.

f0f86627fe VC-1/WMV3 DXVA2 implementation 
It allows VLD VC-1/WMV3 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API.

0c32e19d58 Move +52 from the loop filter to the alpha/beta offsets in the context. 
This should fix a segfault, also it might be faster on systems where the
+52 wasnt free.

87ac0c0a39 Use AVPALETTE_COUNT instead of hard-coding 256. 
This is consistent with other codecs and will also avoid a crash on the
memcpy to data[1] if AVPALETTE_SIZE ever increases.

258b60c224 Gcc idiocy fixes related to filter_mb_edge*. 
Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.
