IPv6 sockaddr clean ups

Browse Source 
This commit address two issues with sockaddr struct implementations for
IPv6:

  1) struct sockaddr_in6 should have 32-bit unsigned field sin6_scope_id
     as specified in Section 3.4 of RFC 3493 (Basic Socket Interface
	 Extensions for IPv6)
  2) struct sockaddr is not extended in IPv6 to contain space for
     struct sockaddr_in6.  Applications should be using struct
	 sockaddr_storage when needing generic storage.  This removes the
	 extra bytes added when LWIP_IPV6 is defined
