[IPV6] MIP6: Add socket option and ancillary data interface of routing header type 2.
Add socket option and ancillary data interface of routing header type 2. Mobile IPv6 application will use this to send binding acknowledgement with the header without relation of confirmed route optimization (binding). Based on MIPL2 kernel patch.
