r22830: merged the latest lib/events updates from ctdb to Samba4. This
includes a new EVENT_FD_AUTOCLOSE flag that prevents race conditions
where code using fd events might close a fd before releasing the
struct fd_event. That causes headaches for epoll.
(This used to be commit f1ad216de13b154a1f8747a44b0970dcc47a784a)
