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)

ac22385931 H.264 idct functions that include the chroma, inter luma and intra16 luma loops 
thus avoiding the calling overhead.

1d217cdb3f Make asf_get_packet() and asf_parse_packet() public for use in RTSP-MS and 
give them a ff_ prefix. See "[PATCH] asf.c: make functions of interest for
MS-RTSP public" thread on ML.

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.
