[gtk/ebassi/run-dialog-run: 107/116] Remove gtk_native_dialog_run()

[Emmanuele Bassi <ebassi src gnome org>]

    Remove gtk_native_dialog_run()
    
    Nested main loops are bad, as they introduce layers of complexity caused
    by the potential re-entrancy in the case of multiple event sources, like
    IPC, threads, etc. Additionally, the programming model they provide—stop
    the world while spinning a new loop—does not conform to the event-driven
    model employed by GTK.

- * gtk_native_dialog_run:
- * @self: a #GtkNativeDialog
- *
- * Blocks in a recursive main loop until @self emits the
- * #GtkNativeDialog::response signal. It then returns the response ID
- * from the ::response signal emission.
- *
- * Before entering the recursive main loop, gtk_native_dialog_run()
- * calls gtk_native_dialog_show() on the dialog for you.
- *
- * After gtk_native_dialog_run() returns, then dialog will be hidden.
- *
- * Typical usage of this function might be:
- * |[<!-- language="C" -->
- *   gint result = gtk_native_dialog_run (GTK_NATIVE_DIALOG (dialog));
- *   switch (result)
- *     {
- *       case GTK_RESPONSE_ACCEPT:

- *          break;
- *       default:
- *          do_nothing_since_dialog_was_cancelled ();
- *          break;
- *     }
- *   g_object_unref (dialog);
- * ]|
- *
- * Note that even though the recursive main loop gives the effect of a
- * modal dialog (it prevents the user from interacting with other
- * windows in the same window group while the dialog is run), callbacks
- * such as timeouts, IO channel watches, DND drops, etc, will
- * be triggered during a gtk_native_dialog_run() call.
- *
- * Returns: response ID
