Michael Paquier 9d33a5a804 xml2: Fix crash with namespace nodes in xpath_nodeset() 
pgxmlNodeSetToText() passed nodeTab[i]->doc to xmlNodeDump() without
checking the node type, which could cause a crash as a
XML_NAMESPACE_DECL maps to a xmlNs struct.  The passed-in code would
then be dereferenced in xmlNodeDump().

This commit switches the code to render XML_NAMESPACE_DECL nodes with
xmlXPathCastNodeToString(), like xpath_table().  Some tests are added,
written by me.
