When clutter actors with key focus are destroyed we emit ::key-focus-out on them just after their destruction. This is against our assumption that no signal should be emitted after "::destroy" (see GNOME/mutter!769 [1]), and in fact could cause the shell to do actions that we won't ever stop on destroy callback. To avoid this to happen, use a private function to set its key-state (so we can avoid looking for the stage) and emit ::key-focus-in/out events and use this value in both clutter_actor_has_key_focus(), clutter_actor_grab_key_focus() and on unmap and destruction to unset the stage key focus before we emit the ::destroy signal. As result of this, we can now avoid to unset the key focus on actor destruction in the stage.
