Robin Gareus ead883302f Don't use shared-pointers in cross thread event structs 
This fixes a deadlock when closing the session.

Session::destroy() takes the engine-lock while removing
unhandled session-events. In [1], the event-queue held a last
reference to a Track, and releasing that object triggered
events (here ~IO) that required the lock.
