Hello all,

The attached patch and additional files add

1) AltiVec flags & tests in "postproc/" and "vf_scale.c"
2) an AltiVec-enhanced yuv2yuvX

The last one may be suboptimal (it certainly eats
quite an amount of memory), but it's roughly 6x-7x
faster than the C code. mencoder display significant
speed gain on some operations, such as transcoding
some codecs to svcd.
