Avoid recursive calling of event callbacks.
When EventLoop::handleEvent() was called recursively (i.e. by calling
processEvents() from a slot), weird things happened, especially in the
XMPP parser (assertion triggers, parse error from server, ...). Now, callbacks
are put in a queue handled by the topmost handleEvent.
Resolves: #592, #568
