Move CAVLC 8x8 DCT special case from ff_h264_filter_mb() to fill_caches

that way it is also available for ff_h264_filter_mb_fast().

Perform reference remapping at fill_cache() time instead of in the

loop filter. This removes one obstacle of getting ff_h264_filter_mb_fast()

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.

~200 bytes smaller ff_h264_filter_mb()
please everyone, NEVER add code with the assumtation that gcc will remove it
without checking gcc actually does. Chances are it does not.

Mark a few functions as noinline, this makes ff_h264_filter_mb() a bit smaller
...
and 5% faster.
ff_h264_filter_mb_fast() stay the same size as gcc decided not to inline these
functions there in the first place.
