On wl_data_source destruction we used to indirectly unset the DnD selection owner via the wl_resource destructor triggering the destruction of the MetaWaylandDataSource, which would be caught through the weak ref set by the MetaWaylandDragGrab. This works as long as the grab is held, however we have a window between the button being released and the drop site replying with wl_data_offer.finish that the MetaWaylandDataSource is alive, but its destruction wouldn't result in the call chain above to unsetting the DnD source. In other selection sources, we let the MetaWaylandDataDevice hold the "ownership" of the MetaWaylandDataSource, and its weak ref functions unset the respective MetaSelection owners. Do the same here, so the MetaWaylandDataSource destruction is listened for all its lifetime. Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591 |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
