Summary: Node.appendChild: raise if ancestor

Initial Comment:
This patch raises a HierarchyRequestErr on an attempt
to appendChild with self or an ancestor.

This is required behavior, and besides, such attempts
were causing hangs during the _4dom_fireMutationEvent
call.

Found when running my PyXML checkout through the
Zope ParsedXML DOM test suite.  With this patch,
PyXML completes the suite without hanging.
