4538729afe Move sine windows to a separate file 
These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

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.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.

82e1f217f2 Rename sf_table in atrac.c unit to ff_atrac_sf_table. 
This ensures a locally-unique name as well as marks the symbol as
FFmpeg-private at least by declaration.

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.
