www cleanup mega commit:

- Move includes.nav*.sgml to share/sgml/navibar.ent and
   <lang>/share/sgml/navibar.l10n.ent.

 - Move includes.sgml and includes.xsl to
   share/sgml/common.ent, share/sgml/header.ent, <lang>/share/sgml/l10n.ent,
   and <lang>/share/sgml/header.l10n.ent.

 - Move most of XSLT libraries to share/sgml/*.xsl and
   <lang>/share/sgml/*.xsl.

 - Move news.xml and other *.xml files for the similar purpose
   to share/sgml/*.xml and <lang>/share/sgml/*.xml.

 - Switch to use a custom DTD for HTML document.  Now we use
   "-//FreeBSD//DTD HTML 4.01 Transitional-Based Extension", which is
   HTML 4.01 + some entities previously pulled via
   "<!ENTITY % includes SYSTEM "includes.sgml"> %includes;" line.
   The location of entity file will be resolved by using catalog file.

 - Add DOCTYPE declearation to XML documents.  This makes the followings
   possible:

   * Use of &foo; entities for SGML in an XML file instead of defining
     {$foo} as the same content.

   * &symbolic; entities for Latin characters.

 - Duplicated information between SGML and XML, or English and
   translated doc, has been removed as much as possible.
