[oden] The big lifetime removal

It turns out that rust can't really reason about the relationship
between the runtime lifetime and the context lifetime in a way that is
actually usable. This removes the lifetime stuff in favor of reference
counting the runtime itself, via a block that we embed in the
pointer. This, I think, it the least worst option here.
