Logging improvements (#1816)

* Add nng_str_sockaddr to get string representation of socket address.

* Added nng_log_get_level() is meant to allow users to obtain the
current level and avoid some possibly expensive operations just
to collect debugging information when debugging is not in effect.

We use a custom logger for NUTS, and this fits within the NUTS
test framework well, so that if -v is supplied we get more content.
All tests now get this by default.
