* qatar/master:
get_bits: remove x86 inline asm in A32 bitstream reader
doc: Remove outdated information about our issue tracker
avidec: Factor out the sync fucntionality.
fate-aac: Expand coverage.
ac3dsp: add x86-optimized versions of ac3dsp.extract_exponents().
ac3dsp: simplify extract_exponents() now that it does not need to do clipping.
ac3enc: clip coefficients after MDCT.
ac3enc: add int32_t array clipping function to DSPUtil, including x86 versions.
swscale: for >8bit scaling, read in native bit-depth.
matroskadec: matroska_read_seek after after EBML_STOP leads to failure.
doxygen: fix usage of @file directive in libavutil/{dict,file}.h
doxygen: Help doxygen parser to understand the DECLARE_ALIGNED and offsetof macros

If you notice errors in the align stuff, need more alignment for some ASM code

for some CPU or need to use a function with less aligned data then send a mail
|
|
to the ffmpeg-devel mailing list, ...
|
|
|
|
!warning These alignments might not match reality, (missing attribute((align))
|
|
stuff somewhere possible).
|
|
I (Michael) did not check them, these are just the alignments which I think
|
|
could be reached easily ...
|
|
|

!future video codecs might need functions with less strict alignment
