Make all handlers objects refcounted.

I'm realizing that basically all upb objects
will need to be refcounted to be sharable
across languages, but *not* messages which
are on their way out so we can get out of
the business of data representations.

Things which must be refcounted:
- encoders, decoders
- handlers objects
- defs
