Time to work on helping the Gnome Doc project, first step is reintegrating
the SGML DocBook parser in libxml2 distrib:
- DOCBparser.c DOCBparser.h testDocbook.c configure.in Makefile.am
  xmlversion.h.in: started (re)integrating the DocBook SGML parser.
- SAX.[ch]: cleanup and updates for DocBook
- debugXML.c parser.h tree.[ch] valid.c xpath.c: small macro or
  ex SGML identifier changes
- valid.c: removed a static unused function.
