Merge remote-tracking branch 'qatar/master'

* 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  doc: Remove outdated information about our issue tracker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
