Avoid race-condition when initializing global locks Previously, we did stuff like if (!lock) EVTHREAD_ALLOC_LOCK(lock,0); for the evsig base global lock, the arc4random lock, and the debug_map lock. But that's potentially racy! Instead, we move the responisiblity for global lock initialization to the functions where we set up the lock callbacks. (Rationale: We already require that you set up the locking callbacks before you create any event_base, and that you do so exatly once.)
