respectively be read from h->mb.pic.p_fdec and h->mb.pic.p_fenc.

Just to make sure the image made of reference blocks would look like a MC one, I
wrote some code you can find in the attached patch. Unfortunately, the produced
images didn't look like what I expected.

Short description of what the patch does:
- add an option to get the residue filename
- initialize output file and output picture buffer
- copy (for now, until I known how to compute residues) for each MB a block of Y
data to the output picture buffer

It does not aim at complying with x264 coding style or be bug-free, though I
could do that if it's worth merging in.

Could someone enlighten me about where the data I'm looking for is located, or
tell me if there's a better way?

Best regards,
Kurosu
