Adding new version of the SAX interface, it's not there yet, currently

* Makefile.am SAX2.c include/libxml/Makefile.am include/libxml/SAX2.h:
  Adding new version of the SAX interface, it's not there yet,
  currently just preparing the work
* globals.c parser.c SAX.c include/libxml/SAX.h
  include/libxml/globals.h include/libxml/parser.h: doing some
  refactoring of the SAXv1 interfaces, obsoleting a bunch of them
  while keeping functionalities, preparing SAX2 integration.
* dict.c: small cleanup.
