The changes to ping.c below are essentially cosmetic, to add
the ability to create an audible reponse to pings, useful for debugging
broken ethernets, among other things. Submitted by Bruce Murphy
<packrat@iinet.net.au>. Are there any objections to this being committed
to -current, and the equivalent to RELENG_2_2?
