The layer_add_notification API accepts a simple wl_listener instead of a ivi-shell specific notification function. Therefore, the API is renamed to layer_add_listener. This change has several advantages: 1. Code cleanup 2. No dynamic memory allocation. Listeners are allocated by controller plugins 3. Remove API is not needed. Controller plugins can easily remove the listener link. This patch also remove two APIs which are not needed: - ivi_layout_layer_remove_notification - ivi_layout_layer_remove_notification_by_callback Signed-off-by: Emre Ucan <eucan@de.adit-jv.com> Reviewed-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
