Fixes out of array reads

This makes the aac decoder and all voice codecs independent of dsputil.

It will be useful in the upcoming transition to refcounted AVFrames.

Also reorder some other #include when applicable.

The function is used elsewhere and does not belong with the LZO code.

As a sideeffect this makes the code more robust if a future change leaves
a path where it may be uninitialized otherwise.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

Also remove one pointless zero initialization in rangecoder.c.

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>.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

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

They are used in lavf.

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.
