Unable to set authNoPriv security level about tnm4j HOT 2 CLOSED

Apparently no one has been using authNoPriv mode, since it's pretty obviously broken. Thanks for reporting it!

The constructor for the UsmUser class in SNMP4j will accept null for the privacy protocol and passphrase. It will also accept null for the auth protocol and auth passphrase.

The fix for this is pretty straightforward.

1. Return null early in the privType method if the priv type specified in v3Target is null. Same change in the authType method.
2. Introduce private privPassphrase and authPassphrase methods that return null if the corresponding type property in v3Target is null or the passphrase is null, otherwise return the passphrase string wrapped in an OctetString. Use the new methods in place of the direct calls to the OctetString constructor in the call to the UsmUser constructor.

If you'd like to get this fixed quickly, you could do a pull request that implements the above changes.

If you don't submit a PR for it, I'll fix myself in a subsequent release the next time I give this project some cycles.
