Store sub_mb_type in direct_cache/direct_table.

This is equal complexity but could be more usefull.

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.

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.
