Export the Transport interface, as there's no reason users shouldn't be
able to define their own transports: they are just bidirectional

Also, add a godoc example for basic Server usage.
Finally, remove some TODOs that existed due to a bad merge: they are
related to the (as yet unsubmitted) streamable HTTP transport.
