[gtk/wip/matthiasc/shortcut-2: 71/117] shortcut: Add GtkShortcutAction



commit 2f0e94ccadb07aa28d0499ecd8f91637a948cda0
Author: Benjamin Otte <otte redhat com>
Date:   Sat Aug 18 07:32:11 2018 +0200

    shortcut: Add GtkShortcutAction
    
    Similar to GtkShortcutTrigger, GtkShortCutAction provides all the
    different ways to activate a shortcut.
    
    So far, these different ways are supported:
    
     - do nothing
     - Call a user-provided callback
     - Call gtk_widget_activate()
     - Call gtk_widget_mnemonic_activate()
     - Emit an action signal
     - Activate an action from the widget's action muxer
     - Activate a GAction

+ * #GtkShortcutAction is the object used to track if a #GtkShortcut should be
+ * activated. For this purpose, gtk_shortcut_action_action() can be called
+ * on a #GdkEvent.
+ *
+ * #GtkShortcutActions contain functions that allow easy presentation to end
+ * users as well as being printed for debugging.
+ *
+ * All #GtkShortcutActions are immutable, you can only specify their properties
+ * during construction. If you want to change a action, you have to replace it
