2x faster ff_h264_init_cabac_states(), 4k cpu cycles less.
...
Sadly this is just per slice so the speedup with normal files should be negligible.

Should be faster as this is a strict code removial.

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.

No benchmark because its just replacing variables with litteral constants
(so no risk for slowdown outside gcc silliness) and i need sleep.
