i think the better solution, which you described, is to replace all the
unneccessary portab types with plain ints. for the asm stuff we should
retain portab types so we dont break the ppc&ia64 code.

dct_t is interesting. i wonder if we could support, through the use of
macros (or templates-style hacks), the use of different coefficient
sizes. x86-mmx works best with 16-bit coefficients, whereas plain ints
are faster on non-simd platforms.

keep in mind: it'd be nice to get the new api into head before any major
cvs-wide changes are applied... it makes merging a royal pain.
