Cleanup CXFA_Node ownership
Currently a CXFA_Node can be owned by the CXFA_Document root pointer,
the CXFA_Document Purge list or as a child of another CXFA_Node. This
makes it hard to know who currently owns what.
This CL moves all ownership of nodes into a CXFA_NodeOwner class which
CXFA_Document subclasses. The node owner always owns all nodes and is
responsible for cleaning them up upon destruction. The destruction order
is not guarenteed to be in tree order as nodes can be inserted and moved
around the tree.
