UDP: Introduce an experimental (undocumented for now) public API for UDP. (#1838)

This exposes the UDP methods as nng_ methods, and adds support for Multicast Membership,
which is useful in a variety of situations.

No documentation is provided, and applications should consider thios API experimental.
