util.roles: Return nil if the role has no explicit policy (fixes inheritance) Previously, if the first inherited role had no opinion, it returned false and prevented further consultation of other inherited roles. This bug was found thanks to the implementation of missing test cases identified through mutation testing.

local record util_timer
	record task end
	type timer_callback = function (number) : number
	add_task : function ( number, timer_callback, any ) : task
	stop : function ( task )
	reschedule : function ( task, number ) : task
end
return util_timer
