s2smanager: Fire s2s-destroyed event to mirror s2s-created The existing events do not fire for unauthed sessions, for example (because the type does not match). I deemed changing their behaviour too risky, and the current behaviour may even be more desirable for some uses. This means we now have roughly paired events: - s2s-created -> s2s-destroyed (global only) - s2sin-established -> s2sin-destroyed (global + host) - s2sout-established -> s2sout-destroyed (global + host)
