Closes #334

... since HTTP is forbidden to return any such.

This patch addresses known bug #76, where on 64-bit Windows SOCKET is 64
bits wide, but long is only 32, making CURLINFO_LASTSOCKET unreliable.

Disabling pipelining on multi handle with in-progress pipelined requests
leads to heap corruption and crash

Use Unix when generically writing about Unix based systems as UNIX is
the trademark and should only be used in a particular product's name.

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.

Reflect recent changes in SPNEGO and GSS-API code in the docs.
Update them with appropriate namings and remove visible spots for
GSS-Negotiate.

...also added as KNOWN_BUG #87 with reference to bug #1294

added 85. Wrong STARTTRANSFER timer accounting for POST requests

CURLINFO_SSL_VERIFYRESULT is only implemented for the OpenSSL and NSS
backends and not for any other!

The old numbers would still redirect but who knows for how long...

Bug: http://curl.haxx.se/bug/view.cgi?id=1169

The test would hang and get aborted with a "ABORTING TEST, since it
seems that it would have run forever." until I prevented that from
happening.

I also fixed the data file which got broken CRLF line endings when I
sucked down the path from Joe's repo == my fault.

Removed #37 from KNOWN_BUGS as this fix and test case verifies exactly
this.

Bug #75 updated with additional info, still remains for builds with
other backends.

Multiple auths in the same WWW-Authenticate header

Fixed in commit 7d81e3f7193b8c

Curl_expire() is now expanded to hold a list of timeouts for each easy
handle. Only the closest in time will be the one used as the primary
timeout for the handle and will be used for the splay tree (which sorts
and lists all handles within the multi handle).

When the main timeout has triggered/expired, the next timeout in time
that is kept in the list will be moved to the main timeout position and
used as the key to splay with. This way, all timeouts that are set with
Curl_expire() internally will end up as a proper timeout. Previously any
Curl_expire() that set a _later_ timeout than what was already set was
just silently ignored and thus missed.

Setting Curl_expire() with timeout 0 (zero) will cancel all previously
added timeouts.

Corrects known bug #62.

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 option as for all other operating systems.
