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.

Move dct and rdft definitions to separate files
...
This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

for calling the fft_calc and related function pointers.

Remove explicit filename from Doxygen @file commands.
...
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
