xml-node: API for manually constructing and outputting XML

Split out RestXmlNode into separate source files and added simple API for
manually constructing tree of RextXmlNodes and converting such a tree to a
string:

 * xml_node_add_child()
 * xml_node_add_attribute()
 * xml_node_set_content()
 * xml_node_print()

Includes xml test for make check
