[mutter/wip/carlosg/clipboard-manager: 22/22] Make MetaSelection, MetaSelectionSource and MetaMemorySelectionSource public

commit c93770213e05e838ae0206f0483f82d80cb8c2f9
Author: Carlos Garnacho <carlosg gnome org>
Date:   Fri Nov 23 11:48:53 2018 +0100

    Make MetaSelection, MetaSelectionSource and MetaMemorySelectionSource public
    
    This exposes the base so that we can reimplement StClipboard on top. Some
    gtk-docs have been added for documentation and introspection purposes.
