Subject: xplist: Assert when number of child nodes of PLIST_DICT is not even

This should only happen due to misuse of the library, e.g. when
calling plist_free() on a node that is a value node in a PLIST_DICT
without properly removing the dictionary entry (key/value pair) and
then calling plist_to_xml() on that dictionary.
