Summary

The default NULL eventhandler forbids unload.

For modules that would like to allow unload, but don't care about module
events, the function "modevent_nop" is exposed. This should allow some
deduplication of identical modevent handler implementations.

See my comments in the other review. markj was just wrong about DRIVER_MODULE. I don't think this is needed.
