rds: Changing IP address internal representation to struct in6_addr
This patch changes the internal representation of an IP address to use struct in6_addr. IPv4 address is stored as an IPv4 mapped address. All the functions which take an IP address as argument are also changed to use struct in6_addr. But RDS socket layer is not modified such that it still does not accept IPv6 address from an application. And RDS layer does not accept nor initiate IPv6 connections. v2: Fixed sparse warnings.
