Fix Yahoo login when using the GnuTLS library for TLS connections.

I changed our gnutls plugin to always treat a closed TCP connection
as if the remote server cleanly terminated the SSL session. I think
it's sad that this is necessary, but I also think it's fairly
harmless. See my comments in the code for details.
