loop filter. This removes one obstacle of getting ff_h264_filter_mb_fast()
bitexact. code is maybe 0.1% faster
Originally committed as revision 21280 to svn://svn.ffmpeg.org/ffmpeg/trunk
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.

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.
