dct: build dct32 as separate object files
...
This builds the float and fixed-point versions of dct32 separately
instead of #including the file in dct.c and mpegaudiodec.c.

dct: bypass table allocation for DCT_II of size 32
...
The size-32 DCT_II has a special implementation which doesn't use
the normal tables. Skipping allocation of these in this case saves
some memory.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.
