[libxml++] Use using instead of typedef

[Kjell Ahlstedt <kjellahl src gnome org>]

commit a1d74cf2b60d17791220c133107fc46ad6f75613

    Use using instead of typedef
    
    * libxml++/document.cc:
    * libxml++/nodes/element.h:
    * libxml++/nodes/node.h:
    * libxml++/parsers/parser.h:
    * libxml++/parsers/saxparser.h:
    * libxml++/parsers/textreader.h: Use using newtypename = oldtype instead of
    typedef oldtype newtypename. This is the recommended way of declaring
    type name aliases in C++11.
