* ext/socket/extconf.rb: use headers instead of "netdb.h" in checking

getnameinfo() and getaddrinfo() because Windows doesn't have it.
	  see [ruby-dev:37757].

	* ext/socket/sockport.h (SA_LEN): use sockaddr_in6 when defined AF_INET6
	  if INET6 is not defined.  winsock2's getaddrinfo() returns
	  sockaddr_in6 if ipv6 is available.
