Add a global rwlock, at_ifaddr_rw, to protect the global netatalk address lists, at_ifaddr_list. Acquire the lock, and use ifaddr refcounts where necessary, to close most known address-related races in netatalk. Annotate one potential race in at_control() where we acquire an ifaddr reference, drop the global lock, and scrub the address from the ifnet before re-acquiring the global lock, which could allow for a writer-writer race.
