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.

2881c83127 Call rdft by function pointer
Call the RDFT by a function pointer like other FFT related transforms.
This makes instruction set optimized versions possible.

Based on patch by Alex Converse.

2ed6f39944 Replace many includes of libavutil/common.h with what is actually needed
This reduces the number of false dependencies on header files and
speeds up compilation.

da0ac0ee64 Make some functions static
These functions are not used outside their respective files, and they
lack a prototype in a header.

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.

4ee726b670 Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitions
for ff_cos_* and ff_sin_* without introducing too much code duplication.

aafd659518 Do not initialize ff_cos_* tables again in rdft_init, they are already
initialized by ff_fft_init and using different code can result in slightly
different values, in addition it crashes when the tables are hardcoded.
On amd64 this slightly changes qdm2 output.

bad5537e2c Use full internal pathname in doxygen @file directives.
Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
