flag for diagonal interpolation

the primary reason for this change is that previously MC up to 1/4 pel
matched H.264 exactly and that increases the risk of stumbling over 
patents

secondary does this allow 0.10 db or more quality gain by choosing a longer
filter and the filter could also be choosen optimally for each frame
though that of course would cause speed loss at the decoder and encoder
side ...

perform interpolation steps in such a order so that halfpel interpolation
could be done per picture
this also make mc_block() match h.264 for the 1/4 pel cases so that the
use of the h264 functions for some cases doesnt inroduce a fantastic mess

if running with multiple threads and CODEC_FLAGS2_FAST is set.
Thus, it may decode the slices in parallel to gain speed.
