  Skip tableprint.h during 'make checkheaders'.
  Remove unnecessary LIBAVFORMAT_BUILD #ifdef.
  Drop explicit filenames from @file Doxygen tags.
  Skip generated table headers during 'make checkheaders'.
  lavf,lavc: free avoptions in a generic way.
  AVOptions: add av_opt_free convenience function.
  tableprint: Restore mistakenly deleted common.h #include for FF_ARRAY_ELEMS.
  tiff: print log in case of unknown / unsupported tag.
  tiff: fix linesize for mono-white/black formats.
  Fix build of eval-test program
  configure: Document --enable-vaapi
  ac3enc: extract all exponents for the frame at once
