[bug-inetutils] libicmp - needs ipv6 support

[Rakesh Pandit]

libicmp currently only supports ipv4 and does not have ipv6 support.
Keeping the interface same and
providing support for ipv6 would make my work for ping/ping6 more
clean. Right now ping module uses
libicmp for ping (IPv4) but for ping6 (IPv6) it does all the crude
work itself, which is wrong.

If libicmp work is done, ping module can be made more clean, and
moreover libicmp has to provide that
support.

Comments and suggestions welcome?
