Ian Dowse c8bb99e577 Certain ICMP error replies cause ping to perform a reverse DNS ...

lookup on an IP address from the packet (such as the IP that sent
a TTL exceeded error). If the DNS lookup takes a long time, ^C will
appear to be ineffective since the SIGINT handler just sets a flag
and returns. Work around this by exiting immediately on receipt of
a second SIGINT when DNS lookups are enabled.
