    ping(8): Relax the interval restriction for normal users
    
    The ping interval was restricted to be >= 1 second for normal users to
    prevent from performing DoS attacks.  This restriction was added by
    Matt Dillon in 1998 during the BEST days [0].  It has become less
    meaningful now.  Following the Linux behavior, relax the interval to be
    >= 2 milliseconds for normal users.
    
    In addition, add a check for negative interval numbers.
