f4060611e9 Merge decode_cabac_mb_type_b() into calling code.
This avoids a conditional branch and is about 3 cpu cyclues faster.

a59b9ee33d Set sub_mb_type in direct_cache instead of just the direct flag.
Simpler, cleaner and faster.

2dc380ca8e Store sub_mb_type in direct_cache/direct_table.
This is equal complexity but could be more usefull.

3d2c3ef4b4 Remove slice_table checks from decode_cabac_mb_cbp_luma() and set left/top_cbp so
these checks arent needed.

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.
