ParserCreate(): Allow an empty string for the namespace_separator argument;
while not generally a good idea, this is used by RDF users, and works
to implement RDF-style namespace+localname concatenation as defined
in the RDF specifications. (This also corrects a backwards-compatibility
bug.)
Be more conservative while clearing out handlers; set the slot in the
self->handlers array to NULL before DECREFing the callback.
Still more adjustments to make the code style internally consistent.
