In the latest sources, http_RequestAndResponse and other methods that
use connect() are broken. More specifically, connect() in these methods is returning with an EINVAL. The programatic cause is that the address_len argument passed to connect() is different in IPV4 vs IPV6 (as described in: http://www.opengroup.org/onlinepubs/009695399/functions/connect.html). The current code always uses the IPV6 size. The fix modifies each use of connect() to use the correct size based on the address family being used. Patch submitted by Chandra (inactiveneurons).

Fix compilation error in upnp/src/gena/gena_ctrlpt.c (this is most

likely an error on all platforms).
