same speed as far as i can meassure but it might have fewer branches on some archs. Idea from x264 / jason Originally committed as revision 22027 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.
