8955b66950 Optimize ctx calculation in decode_cabac_mb_mvd(), code by dark shikari. 
The case for 16x16 blocks becomes 10 cpu cycles faster on pentium dual,
i could not find a speed difference in the case of subblocks though.

for future optimizations.

2fd1f0e026 Use the new idct functions (except chroma as it was slower in benchmarks) 
cathedral +0.5% speed
aladin +0.6% speed [note aladin has been cat-ed 10 times to reduce the influence
of init time]
Speedup also verified via START/STOP_TIMER (difference was very significant
for the changed parts)
