Mans Rullgard 6f2309ed2e 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.

Mans Rullgard 721d6f2dc5 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.

Mans Rullgard 0aded9484d 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.

Mans Rullgard 26f548bb59 fft: remove inline wrappers for function pointers
This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

Vitor Sessak 06d01188e9 More mp{1,2,3} 32-point DCT transform to our common DCT framework.
Should allow for future SIMD optimizations.

Diego Biurrun ba87f0801d 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.
