599fe45b8d Split fill_caches() between loopfilter & decode, the 2 no longer where common 
enough to justify the messy interleaving.

c988f97566 Rearchitecturing the stiched up goose part 1 
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.

ddd60f28d8 Replace cabac checks in inline functions from h264.h with constants. 
No benchmark because its just replacing variables with litteral constants
(so no risk for slowdown outside gcc silliness) and i need sleep.

7c2de274e7 Add forgotten include of h264_mvpred.h to h264.h. 
This could have caused the linking failure of pred_pskip_motion() missing if
a compiler included never used static functions.

e1e949026e Split cavlc out of h264.c. 
Seems to speed the code up a little...
The placement of many generic functions between h264.c and h264.h is still open
Currently they are a little randomly placed between them.

2bedc0e854 Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just 
called once per MB in worst case and doesnt seem to benefit from static inline.
Actually the code might be a hair faster now (0.1% according to my benchmark but
this could be random noise)

903d58f631 Get rid of #include "svq3.c" 
functions called more than per mb are moved into the header, scan8 is also
as it must be known at compiletime.
The code after this patch duplicates h264data.h, this has been done to minimize
the changes in this step and allow more fine grained benchmarking.
Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral
sample.
