[libxml++] Replace xmlpp::NodeSet by xmlpp::Node::NodeSet

[Kjell Ahlstedt <kjellahl src gnome org>]

commit a640bf9548ccb67d59cc168fd651145169e55414

    Replace xmlpp::NodeSet by xmlpp::Node::NodeSet
    
    * libxml++/nodes/node.[h|cc]: Declare the NodeSet and const_NodeSet typedefs
    inside class Node. That's consistent with how Node::NodeList, Node::PrefixNsMap
    and Element::AttributeList are declared.
