Commit Message

Commit ff12cd6 "handlers: associate each handler with a mask"
introduced handler masks to designate handlers to particular
types. Make this enum available for Lua handler registration.

Per default, a Lua handler will be registered as ANY_HANDLER.
The optional 3rd argument to l_register_handler() allows to
specify otherwise.
