Wayland: Fix various compiler warnings

Mostly missing declarations, missing statics and unused functions.

- * gdk_wayland_display_broadcast_startup_message:
- * @display: a #GdkDisplay
- * @message_type: startup notification message type ("new", "change",
- * or "remove")
- * @...: a list of key/value pairs (as strings), terminated by a
- * %NULL key. (A %NULL value for a key will cause that key to be
- * skipped in the output.)
- *
- * Sends a startup notification message of type @message_type to
- * @display. 
- *
- * This is a convenience function for use by code that implements the
- * freedesktop startup notification specification. Applications should
- * not normally need to call it directly. See the 
- * [Startup Notification Protocol specification](http://standards.freedesktop.org/startup-notification-spec/startup-notification-latest.txt)
- * for definitions of the message types and keys that can be used.
- *
- * Since: 2.12
