Move disconnect_all to CommonInterface and implement in clients.

Factor out process thread implementation of Disconnect into Disconnect::Impl.
Implement DisconnectAll in terms of DisconnectImpl rather than abusing Disconnect.
Dramatically reduce notification communication overhead of DisconnectAll.
