Add ip6addrctl_enable and ip6_addrctl_verbose option. If
ip6addrctl_enable is set to YES, address selection policy is installed into kernel. If there is /etc/ip6addrctl.conf, it is used for address selection policy. Even if there is no /etc/ip6addrctl.conf, we install default policy. In this case, if ipv6_enable is set to YES, we use address selection policy described in RFC 3484 as default. Otherwise, we install priority policy for IPv4 address. The default of ip6addrctl_enable is NO for now. However, it may better to enable it by default.
