Transfer ownership of nodes to top-level XML doc
For XFA, XML nodes are owned by the XML doc that they were created by,
but references to them are stored elsewhere. For a PDF document there
is one top-level XML document created and retained when the initial
XFA XML is parsed. Another can be created if loadXML is called by
JS. In the existing code the XML doc that owns the newly created nodes
is local to loadXML. So the nodes are destroyed right after putting
refernces to them into the main XFA data structures.
This CL adds in a method to transfer ownership of the XML nodes from
one doc to another, and uses it to correctly retain the newly created
nodes, by having them owned by the top-level XML doc.
