Fix a potentially very annoying evdns bug that we found in Tor. Generally speaking, it way better to event_assign() an event when you allocate it than to assign it before every time you event_add it: if it is already event_add()ed, the assign will mess it up so that it doesn't _look_ added, and event_add() will insert a second copy. Later, event_del() will only delete the second copy. Eventually, the event_base will have a dangling pointer to freed memory. Ouch! svn:r1308
