Subject: [mutter/gnome-3-36] wayland: Move the primary data device manager to its own file
Date: Wed, 24 Jun 2020 20:21:38 +0000 (UTC)
commit e98e1c13dd6ecaea61f8ddb0d9edf8ebe4c03f7d
Author: Carlos Garnacho <carlosg gnome org>
Date:   Thu Apr 9 17:51:59 2020 +0200

    wayland: Move the primary data device manager to its own file
    
    Instead of having everything clumped at MetaWaylandDataManager,
    split the primary selection to its own struct. This manager is
    handled separately from wl_data_device_manager and other selection
    managers, so they would be able to interoperate between them, even.
