When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for
ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate
files. Other codecs are affected to a lesser extent because they are
less optimized; e.g., VC-1 slows down by less than 1% (all on x86).
The patch generated 3 extra instructions (cmp, cmovae and mov) per
call to get_bits().
The performance penalty on ARM is within the error margin for most
files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264.
Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and
inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.

this allows for checking against the actual output size instead of max size.

It's more readable and less prone to breakage.

Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.
Additionally, this commit streamlines some spelling and appearances.

sizeof(array_functrion_argument) gives the size of the pointer type not
the size of the array to which it points.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

None of these symbols should be accessed directly, so declare them as
hidden.

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.
