    net: make resolveInternetAddr return a list of addresses · 7c59c8bd
    Mikio Hara authored
    This CL makes resolveInternetAddr return a list of addresses that
    contain a pair of different address family IP addresses if possible,
    but doesn't contain any API behavioral changes yet. A simple IP
    address selection mechanism for Resolve{TCP,UDP,IP}Addr and Dial API
    still prefers IPv4.
    
    This is in preparation for TCP connection setup with fast failover on
    dual IP stack node as described in RFC 6555.
