Edit init-functions

1. including the pid number in messages, as a double check that status is identified correctly.
2. removed -p option from pidfile variable, as it can create confusion, pidfile is "$pidfile" and not "-p $pidfile"
3. introduced status 3
4. detect zombies. status=0 and not running, or running but not status=0
5. messages always terminate with \n else they concatenate ugly.
