[gtk/wip/otte/listview: 876/1040] gdk: Add GDK_DECLARE_EXPORTED_TYPE()

commit 47ba7fc0ac258020971e315f0da8aa87ad2e7302
Author: Benjamin Otte <otte redhat com>
Date:   Wed Dec 11 20:03:00 2019 +0100

    gdk: Add GDK_DECLARE_EXPORTED_TYPE()
    
    This is like G_DECLARE_FINAL_TYPE(), except it doesn't make the class
    struct public, so internally all the subclassing in the world can
    happen.
    
    Some subtle differences:
    - It marks the get_type() function as G_GNUC_CONST
    - It doesn't require the parent type
    - It uses G_DEFINE_AUTOPTR_CLEANUP_FUNC() instead of the private glib
      chainup method.
    
    Port a bunch of GDK and the whole event controller + gesture machinery
    to provew that it works.
    
    As a side effect, we gained a bunch of missing autocleanups.
