scanner: use destructor event annotations

Browse Source 
Make use of destructor annotations on events to generate more robust
server code. It's now impossible to forget e.g. the required
wl.Callback.destroy() call after wl.Callback.sendDone() since now there
is no wl.Callback.sendDone(), only wl.Callback.destroySendDone().
