465c9fdeeb Remove pointless HAVE_ALTIVEC #ifdefs from a file that only contains AltiVec 
optimizations and no general PPC optimizations. Instead make the file be
compiled conditional to HAVE_ALTIVEC.

7d7f57d939 store halfpel filter coefficients in the header as well as the 
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

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

perform interpolation steps in such an order that halfpel interpolation
could be done per picture
this also makes mc_block() match h.264 for the 1/4 pel cases so that the
use of the h264 functions for some cases does not introduce a fantastic mess
