pcuif_proto: version 10: add support for IPv6 NSVCs
Introduce a address_type in the NSVC configuration pass the given protocol. The remote_ip is network byte order, the default encoding for in_addr and in6_addr. Related: Iae854875a45dbc29cd46a267ccaf60f1f2ac2973 Related: SYS#4915 Change-Id: I740be0a401612bb5ed4e8ccd7f4be8176b936449
