04824298a9 Faster CAVLC decoding of trailing_ones. Based on a patch by dark shikari. 
decode_residual is about 3.3% faster.

93445d1617 Replace i by trailing_ones, part of a patch by dark shikari. 
No speed change meassureable with START/STOP_TIMER, but this is needed
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)
