[stunnel-users] service reconfiguration by SIGHUP

It won't work for privileged ports if you are using setuid/setgid options,
since the original privileges are dropped after the initial set of ports are
bound. If you do not set this option, then it shouldn't make a difference
(as long as the original user has permission to bind priv ports, e.g. root).
The chroot parameter would also limit the functionality of this patch. You
would need to copy or hard link the config file into the chroot'ed directory

Established connections are not closed, only the listening ports are closed
and opened. This is confirmed through my own testing.
