Ticket 527 - ns-slapd segfaults if it cannot rename the logs
    
    Bug Description:  If we can not rename a log file, triggered by log rotation,
                      we try and log a message stating this error, but trying to
                      log this new message triggers log rotation again.  This leads
                      to an infinite loop and a stack overflow.
    
    Fix Description:  Created a new logging function that does not do a rotation check.
                      We use this new function for all emergency error logging.
