Lennart Poettering 58ea275a68 core: introduce new KillMode=mixed which sends SIGTERM only to the main process, but SIGKILL to all daemon processes
This should fix some race with terminating systemd --user, where the
system systemd instance might race against the user systemd instance
when sending SIGTERM.
