cleaned up the build process to remove all remains from the old gtk-doc

* doc/Makefile.am doc/*.xsl doc/*.html doc/apibuild.py: cleaned up
  the build process to remove all remains from the old gtk-doc
  inherited, libxml2-refs.xml is now generated by apibuild.py, the
  stylesheets have been improved, and the API*html now generated
  are XHTML1 valid too
