Add an access control driver that uses the pkcheck command to check authorization requests. This is fairly inefficient, particularly for cases where an API returns a list of objects and needs to check permission for each object. It would be desirable to use the polkit API but this links to glib with abort-on-OOM behaviour, so can't be used. The other alternative is to speak to dbus directly Signed-off-by: Daniel P.
