2018-10-15supervise-daemon: fix respawn_max off by oneZac Medico
Fix the comparison between respawn_count and respawn_max so that respawn_max = 1 will allow for one respawn. Since respawn_count is incremented before the comparison, use a 'greater than' comparison so that respawn will be triggered when respawn_count is equal to respawn_max.

2017-10-27supervise-daemon: use RC_SVCNAME as the first argument to the daemonWilliam Hubbs
This makes ps show which service the supervisor is monitoring.

2017-10-26supervise-daemon: log with the service name instead of "supervise-daemon"William Hubbs
2017-10-26supervise-daemon: remove child_pid from saved options during shutdownWilliam Hubbs
This allows us to detect when the supervisor dies unexpectedly because in that case child_pid will still exist.

2017-10-24supervise-daemon: multiple fixesWilliam Hubbs
- 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
2017-10-18supervise-daemon: elevate some log messages to warningsWilliam Hubbs
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.
2017-09-18ignore sigchld when shutting down the supervised processWilliam Hubbs
We need to do this to skip the zombie state for the child process since we are not easily able to wait() for it.

2017-09-18supervise-daemon: code cleanupWilliam Hubbs
Clean up the process for killing an active supervisor when stopping.
2017-09-14add quiet switch to do_stop in src-schedules.cWilliam Hubbs
This allows supervise-daemon to run this code without attempting to print some status messages used by start-stop-daemon.
2017-09-06add quiet parameter to run_stop_scheduleWilliam Hubbs
2017-09-06add retry option to supervise-daemonWilliam Hubbs
The --retry option for supervise-daemon defines how the supervisor will attempt to stop the child process it is monitoring. It is defined when the supervisor is started since stopping the supervisor just sends a signal to the active supervisor. This fixes #160.

2017-05-11supervise-daemon: fix our status when we give up on the child processWilliam Hubbs
2017-05-10supervise-daemon:create multiple options from --respawn-limitWilliam Hubbs
This creates --respawn-delay, --respawn-max and --respawn-period. It was suggested that it would be easier to follow if the options were separated. This is for #126.
2017-05-09supervise-daemon: add a --respawn-limit optionWilliam Hubbs
Allow limiting the number of times supervise-daemon will attempt to respawn a daemon once it has died to prevent infinite respawning. Also, set a reasonable default limit (10 times in a 5 second period). This is for issue #126.
