ping: do reverse DNS lookup of the target address

Description

ping: do reverse DNS lookup of the target address

When printing replies, ping will now attempt a reverse DNS lookup of the
target. That can be suppressed by using the "-n" option. Curiously, ping
has always done reverse lookups in certain error paths, but never in the
success path.
