NFS: Adjust nfs_clone_mount structure to store "struct sockaddr *"
Change the addr field in the nfs_clone_mount structure to store a "struct sockaddr *" to support non-IPv4 addresses in the NFS client. Note this is mostly a cosmetic change, and does not actually allow referrals using IPv6 addresses. The existing referral code assumes that the server returns a string that represents an IPv4 address. This code needs to support hostnames and IPv6 addresses as well as IPv4 addresses, thus it will need to be reorganized completely (to handle DNS resolution in user space).
