* ext/socket/option.c (inspect_ipv6_mreq): new function to inspect
struct ipv6_mreq for IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP.
Socket::Option.new(:INET6, :IPV6, :JOIN_GROUP,
[0xff12,0,0,0,0,0,0,1, 2].pack("nnnnnnnnI!")).inspect is now:
"#<Socket::Option: INET6 IPV6 JOIN_GROUP ff12::1 eth0>"
* ext/socket/extconf.rb: check struct ipv6_mreq.
