net: ipv6: Implement /proc/net/icmp6.
The format is based on /proc/net/icmp and /proc/net/{udp,raw}6. Compiles and displays reasonable results with CONFIG_IPV6={n,m,y} Couldn't figure out how to test without CONFIG_PROC_FS enabled. Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
