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)

d7fb5a18fc Add a ByteIOContext argument to ASF functions that will be shared with the 
RTSP stack for RTSP-MS support. This way, they can read input from any given
input source. See discussion in "[PATCH] add gb argument to ASF functions of
interest to MS-RTSP" ML thread.
