d56668bd80 floatdsp: move scalarproduct_float from dsputil to avfloatdsp. 
This makes the aac decoder and all voice codecs independent of dsputil.

594d4d5df3 lavc: add a wrapper for AVCodecContext.get_buffer(). 
It will be useful in the upcoming transition to refcounted AVFrames.

8cfbbd928c get_bits: introduce safe bitreading to prevent overreads. 
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>.

21a19b7912 doxygen: Prefer member groups over grouping into modules 
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.
