FFT in MIPS implementation is working iteratively instead
 of "recursively" calling functions for smaller FFT sizes.
Some of DSP and format convert utils functions are also optimized.

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.

This reduces the number of false dependencies on header files and
speeds up compilation.

While this "wastes" up to 2x32 bytes it makes the code slightly simpler and
less confusing.

--enable-hardcoded-tables was used.
Due to the size, the code for the tables is generated at compile time.

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.
