refactor initialization/finalization

Applications must now call nng_init(), but they can supply
a set of parameters optionally.  The code is now safe for
multiple libraries to do this concurrently, meaning nng_fini
no longer can race against another instance starting up.

The nni_init checks on all public APIs are removed now.
