mod_http_oauth2: Namespace the various codes to minimize confusion Both for the programmer and in OAuth flows. While unlikely, it should not be possible to cause weirdness e.g. by typing a client id and authorization code into the device code entry.

module:hook("authentication-success", function (event)
	local session = event.session;
	local sasl_handler = session.sasl_handler;
	session.log("info", "Authenticated with %s", sasl_handler and sasl_handler.selected or "legacy auth");
end);
