Added nn_compat code for option handling, fixed other bugs.

Hop counts for REQ were busted (bad TTL), and imported the
compat_reqtll test. At the same time, added code to nn_term
to shut down completely, discarding sockets.  (Note that some
things, such as globals, may still be left around; that's ok.)
