It's nicer if the child process gets reinitialized cleanly instead of
the parent process.

Use them only for systemctl status.

service: when after startup only one process is in a service's cgroup, assume it is the main process

This patch adds a cpp definition HAVE_SYSV_COMPAT that is used to
isolate code dealing with /etc/init.d and /etc/rcN.d for systems where
it does not make sense (one that does not use sysv or one that is fully
systemd native).

The patch tries to be as little intrusive as possible, however in
order to minimize the number of #ifdef'ed regions I've reordered some
code in path-lookup.c:lookup_paths_init() where all code dealing with
sysv is now isolated under running_as == MANAGER_SYSTEM as well.

Moreover, In struct Service, some fields were rearranged to reduce
the number of ifdefs.

Lennart's suggestions were fixed and squashed with the original patch,
that was sent by Gustavo Sverzut Barbieri (barbieri@profusion.mobi).

"condrestart" should be equivalent to "try-restart", i.e. it should be
translated into "TryRestartUnit". See
