Provide all licenses used in the project in a LICENSES folder and
add SPDX license and copyright information for all files in
accordance with the Reuse Software[0] specification.
The copyright information is based on the file's git history,
using a fairly generous definition of "non-trivial".
As of the spec recommendation, the information is generally added
as comments in the files themselves, except for
- NEWS, README and similar top-level standard files, so that
a SPDX code isn't the first thing people encounter
- files that don't support comments (json) or where they'd
be a bit awkward (.desktop, .service)
- anything under po/, to not interfere with translation teams
Those are covered by a .reuse/dep5 files, except for image assets,
where separate .license files are used (It would be possible to
add comments to SVG files, but I don't trust image editors to
preserve them).

The regular GNOME session ships with three options:
* GNOME
* GNOME on Wayland (available when GDM starts in X11)
* GNOME on Xorg (available when GDM starts in Wayland)
The main GNOME session is set up so it works to match how GDM starts,
so GNOME is on Wayland if GDM is (or GNOME is on X11 if GDM is).
For GNOME Classic, we are missing this setup, so port this behavior
over from the GNOME session setup.
