[OpenDivX] calculation of SAD in SubPel

[Christoph Lampert <lampert@math.chalmers.se>]

Hi,

in the routine for subpixel-ME FindSubPel() in ./encore/src/mot_est_mb.c 
there is a "hard-encoded" calculation of SAD, line 799ff
(called AE=absolute error there)

Maybe this should be changed to a call to a standard routine 
from ./encore/src/mot_util.c, or a special new one there, so it will 
be not be forgotten when optimizing for MMX/SSE/VIS. 

Btw. there is an MMX-optimized SAD routine postet to the Encoders-Forums.
