Michael Niedermayer 27ef7b1bcd Merge remote-tracking branch 'newdev/master'
* newdev/master:
  mov: set audio service type for AC-3 from bitstream mode in the 'dac3' atom.
  Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parser and decoder, and vice-versa for the AC-3 encoder.
  Use audio_service_type to set stream disposition.
  Add APIchanges entry for audio_service_type.
  Add audio_service_type field to AVCodecContext for encoding and reporting of the service type in the audio bitstream.
  configure: in check_ld, place new -l flags before existing ones
  support @heading, @subheading, @subsubheading, and @subsubsection in texi2pod.pl
  doc: update build system documentation
  aacenc: indentation
  aacenc: fix the side calculation in search_for_ms
  vp8.c: rename EDGE_* to VP8_EDGE_*.

Conflicts:
	doc/APIchanges
