worker_free() did not clear worker->event->worker, leaving an event that was still attached to a worker pointing at freed memory once the worker was gone. manager_free() frees the workers (hashmap_free()) before it walks manager->events to process them, and event_free() then writes event->worker->event = NULL into the already-freed worker. Clear the back-pointer in worker_free(), mirroring event_free() which already clears the worker's pointer. The link used to be torn down by the event_free(worker->event) call in worker_free(), which was dropped when events became reference counted. The Event and Worker definitions move to udev-manager.h (next to Manager) so the unit test can construct and free a bound worker/event pair.
