- constructors for bus messages should probably not be OK with a NULL bus pointer
- - sd_bus_escape_label() should probably be reworked into sd_bus_make_bus_path(prefix, external_id)
- .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
