Merged requested to merge guido.gunther/wlroots:0.14.x-xdg-activation into librem5-0.14.x
Allows the compositor to submit tokens to the pool of currently active tokens. This can be useful when the launcher doesn't use or support xdg-activation-v1 by itself - e.g. when it is X11 based or use gtk_shell1.
This is needed until we switch to 0.15.x.
