Subject: [PATCH] NTLM: ignore CURLOPT_FORBID_REUSE during NTLM HTTP auth
Problem: if CURLOPT_FORBID_REUSE is set, requests using NTLM failed
since NTLM requires multiple requests that re-use the same connection
for the authentication to work
Solution: Ignore the forbid reuse flag in case the NTLM authentication
handshake is in progress, according to the NTLM state flag.
Fixed known bug #77.

-77. CURLOPT_FORBID_REUSE on a handle prevents NTLM from working since it
- "abuses" the underlying connection re-use system and if connections are
- forced to close they break the NTLM support.

76. The SOCKET type in Win64 is 64 bits large (and thus so is curl_socket_t on
that platform), and long is only 32 bits. It makes it impossible for
curl_easy_getinfo() to return a socket properly with the CURLINFO_LASTSOCKET
