This generator can be used by desktop environments to launch autostart applications and services. The feature is an opt-in, triggered by xdg-desktop-autostart.target being activated. Also included is the new binary xdg-autostart-condition. This binary is used as an ExecCondition to test the OnlyShowIn and NotShowIn XDG desktop file keys. These need to be evaluated against the XDG_CURRENT_DESKTOP environment variable which may not be known at generation time. Co-authored-by: Henri Chain <henri.chain@enioka.com>
