82da844b42 implement "unsupervised" status 
The unsupervised status is to be used when a supervisor of a supervised
service dies but leaves the service daemon itself running.

667a09983c supervise-daemon: remove child_pid from saved options during shutdown 
This allows us to detect when the supervisor dies unexpectedly because
in that case child_pid will still exist.

cf429ee359 rc_service_value_set: remove the option if NULL is the value

35b88fb42b cgroups_cleanup: clean up shutdown signaling 
- do not sleep for the full 90 seconds if processes are dead
- re-arrange the order of signals we attempt to send to the processes

a428c325a9 add "unsupervised" status and return code 64 to supervise-daemon status function 
This is to be used if the service is being supervised and the
supervisor is somehow killed.

Currently, this is very linux specific, but I will expand to other
platforms, patches are welcome.

fdce4769f2 supervise-daemon: multiple fixes 
- Harden against dying by handling all signals that would terminate the
program and adding --reexec support
- factor the supervisor into its own function
- fix test for whether we are already running

35b1996704 supervise-daemon: elevate some log messages to warnings 
Prior to this change, we were logging unexpected terminations of daemons
we were supervising at the info level. This change moves the logs to
warnings.

efa9ba485d init.d/sysfs.in: fix reference to RC_LIBEXECDIR 
The sysfs init script referred to @LIBEXECDIR@ before this change, but
it is better to refer to RC_LIBEXECDIR so that we get rid of a sed
substitution.

3c05db74f6 remove service binary 
The service binary was just a synonym for rc-service, so use rc-service
instead of service. If you want a "service" binary, it should be
something that can determine which service manager you are running and
run the appropriate service manager commands.

1cac8b080c ignore sigchld when shutting down the supervised process 
We need to do this to skip the zombie state for the child process since
we are not easily able to wait() for it.

2b0345165e Make cgroup_cleanup send only one sigterm and sigkill 
Instead of looping and sending multiple signals to child processes in
cgroup_cleanup, we send sigterm followed by sleeping one second then
sigkill.

This brings us more in line with systemd's "control group" killmode
setting.

Also, this commit includes several shellcheck cleanups.
