Allow ``set server closed'' to close the diagnostic socket.

Allow ``set server open'' to re-open the diagnostic socket.
Handle SIGUSR1 by re-opening the diagnostic socket
When receiving SIGUSR2 (and in ``set server none''), don't forget the
socket details so that ``set server open'' and SIGUSR1 open it again.

Don't create the diagnostic socket as uid 0 !  It's far to dangerous.
