  lavc: fix documentation for AVCodecContext.delay
  atrac3: return an error if extradata_size is not a specific known size
  lavc: use the correct API version guard macro for avcodec_encode_audio()
  Move Doxyfile into the doc/ subdirectory
  doxygen: Build Doxygen documentation in the doc/ subdirectory
  dfa: use av_memcpy_backptr() where previously impossible
  av_memcpy_backptr: Drop no longer necessary malloc padding
