    _______________________________________________________

Details:

When using a dual stack the type field was not being set when copying socket
addresses, and so subsequent users of the ip_addr_t would more than likely
treat an IPv6 address as a 32-bit IPv4 (since current macros default to IPv4
when type != IPADDR_TYPE_V6 and the uninitialised field could be anything
depending on the underlying run-time).

Simple patch attached (since easier doing it in this dual stack only function
than in the SOCKADDR#_TO_IP#ADDR_PORT macros).
