[XFRM] STATE: Add a hook to find offset to be inserted header in outbound.
On current kernel, ip6_find_1stfragopt() is used by IPv6 IPsec to find offset to be inserted header in outbound for transport mode. (BTW, no usage may be needed for IPv4 case.) Mobile IPv6 requires another logic for routing header and destination options header respectively. This patch is common platform for the offset and adopts it to IPsec. Based on MIPL2 kernel patch.
