Carlos Santos b3c76a435b sysklogd: rewrite init script
- Split it into S01syslogd and S02klogd to make every init script be
  called the same as the executable it starts.
- Implement start, stop, restart and reload as functions, like in other
  init scripts, using start-stop-daemon.
- Indent with tabs, not spaces.
- Detect and report start/stop errors (previous version ignored them and
  always reported OK).
- Support /etc/default/$DAEMON configuration files.
- Do not kill syslogd in "reload". Send a SIGHUP signal, instructing it
  to perform a re-initialization.
- Do not kill klogd in "reload". Send a signal (default 0, which does
  nothing).  Users can configure this signal in /etc/default/klogd to
  either SIGUSR1 or SIGUSR2.
