    gtlsclientconnection: use-ssl3 is now ignored
    
    For many years after SSL 3.0 support was removed, we used this function
    to indicate that we should perform protocol version fallback to the
    lowest-supported protocol version, to workaround protocol version
    intolerance. Nowadays this is no longer needed, and support has been
    removed from glib-networking, so update the documentation.
