Change semantics for SysV start/stop scripts

If a start/stop script returns OK we classify it as 'started' and leave
it in running state, despite having collected its PID.  This way we can
track what scripts need to be called with 'stop' when changing to a
runlevel they are not declared for.

Also, clean up related debug messages from earlier commit.
