yuv2rgb_mmx crashes with ffdivx codec, when we play back avi files that have
a frame width that is not an exact multiple of 8.
Testcase: 405.avi (356x240). Playing on an MMX capable x86 system using the
x11 video-out driver results in a segfault.
The MMX routines convert image data in quantities of 8 pixels in each loop,
and the inner loop was not terminated in case there are only 1-7 pixels left,
producing too much RGB output.
For now, just ignore the last few pixels on each row, to avoid the segfaults.
(Gives a black vertical border on the right, if you play a video with
width%8 != 0) A possible future enhancement would be, to add a second loop
to convert the last width%8 pixels to RGB using a byte loop.
