    Add dbus-update-activation-environment tool · 2a6cefbc

    If OS builders (distributions) have chosen to use the per-user bus,
    this provides two possible modes of operation for compatibility with
    existing X session startup hooks.
    
    A legacy-free system can just upload DISPLAY, XAUTHORITY and possibly
    DBUS_SESSION_BUS_ADDRESS into dbus-daemon's and systemd's activation
    environments, similar to
    http://cgit.freedesktop.org/systemd/systemd/tree/xorg/50-systemd-user.sh
    installed by systemd (but unlike systemctl,
    dbus-update-activation-environment works for traditional
    D-Bus-activated services, not just for systemd services).
    
    A system where compatibility is required for environment variables
    exported by snippets in /etc/X11/xinit/xinitrc.d (in Red Hat derivatives,
    Gentoo, etc.) or /etc/X11/Xsession.d (Debian derivatives) can upload
    the entire environment of the X session, minus some selected environment
    variables which are specific to a login session (notably XDG_SESSION_ID).
    
    In Debian, I plan to put the former in a new dbus-user-session package
    that enables a user-session-centric mode of operation for D-Bus,
    and the latter in the existing dbus-x11 package, with the intention that
    dbus-x11 eventually becomes a tool for change-averse setups or goes
    away entirely.
