[IPV6] ADDRCONF: Mobile IPv6 Home Address support.
IFA_F_HOMEADDRESS is introduced for Mobile IPv6 Home Addresses on Mobile Node. The IFA_F_HOMEADDRESS flag should be set for Mobile IPv6 Home Addresses for 2 purposes. 1) We need to check this on receipt of Type 2 Routing Header (RFC3775 Secion 6.4), 2) We prefer Home Address(es) in source address selection (RFC3484 Section 5 Rule 4).
