41327cca61 FFT: simplify fft8()
Part of the fft8() function corresponds to the BUTTERFLIES macro,
so use it.

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.

1ffc6e8327 Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that the
necessary ff_cos_tabs tables are initialized.
Fixes issue 1507 (QDM2 broken since r20237 without hardcoded tables).

223217746c Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits.
While this "wastes" up to 2x32 bytes it makes the code slightly simpler and
less confusing.

16aec74761 Use hardcoded instead of runtime-calculated ff_cos_* tables if
--enable-hardcoded-tables was used.
Due to the size, the code for the tables is generated at compile time.

46c32e2654 Prepare for optimised forward MDCT implementations
This adds a function pointer for forward MDCT to FFTContext and
initialises it with the existing C function.  ff_calc_mdct() is
changed to an inline function calling the selected version as
done for other fft/mdct functions.
