When connecting to a VMWare server, the hostname from URI is resolved using esxUtil_ResolveHostname() which in turn calls getaddrinfo(). But in the hints argument, we restrict the return address to be IPv4 (AF_INET) which obviously fails if the address to resolve is an IPv6 address. Set the hint to AF_UNSPEC which allows both IPv4 and IPv6. While at it, also allow IPv4 addresses mapped in IPv6 by setting AI_V4MAPPED flag.
