gss-server.c (main, sign_server): Make changes to allow
	gss-server to be fired out of inetd.  New options: -inetd
	and -logfile.  The -logfile allows the output of
	gss-server to be redirected to a file.

gss-misc.c (send_token, recv_token, display_status_1): Add
        support for -logfile option.  If the external FILE
	*display_file is set, redirect error messages to
	display_file instead of stderr.
