clipboard: Introduce GdkContentProvider
GdkContentProvider is the object that represents local data in the clipboard. This patch only introduces the object and adds the clipboard properties, it does not yet provide a way for the actual implementations to access it. The only access that is implemented is the local shortcut GValue access.
