-Commit: William Hubbs <w.d.hubbs@gmail.com>
-
-    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.

-
-    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.

-
-    rc_service_value_set: remove the option if NULL is the value
-    
-    This allows the equivalent of "unsetting" a value for a service.

-commit a428c325a902bba55a849a07a59c0c1567404db2
-Author: William Hubbs <w.d.hubbs@gmail.com>
-Commit: William Hubbs <w.d.hubbs@gmail.com>
-
-    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.
