That patch only updated the unix sockets code - the winsock code was not
updated and no longer works the same was as the unix code. This change
updates the windows code accordingly.

Inclusion of header "memdebug.h" in http_ntlm.c got lost in commit 98fb0ef7.

Bug: http://curl.haxx.se/bug/view.cgi?id=3383692

Strict splitting of http_ntlm.[ch] may trigger 8 compiler warnings when
building with some compilers and strict compiler warnings enabled, depending
on other specific configuration options some could get triggered or not.

Seven are related with 'unused function parameters' and another one with
'var may be used before its value is set'.

For modularity purposes, huge chunks of NTLM existing code is transformed into
functions to allow future internal code reuse.

Resulting three new libcurl private functions:

 - Curl_ntlm_create_type1_message()
 - Curl_ntlm_create_type3_message()
 - Curl_ntlm_decode_type2_message()

Changing static ntlm_sspi_cleanup() into non-static Curl_ntlm_sspi_cleanup()

This 'refactoring' has been prepared by previous commits to allow that this
specific one does not introduce any change to existing code. All existing
goodness and badness previous to this commit should remain the same once it is
applied, the only difference should be that existing code is moved into
functions.

Given the quite big portions of code being moved around, and the importance of
change traceability, this commit has been done in such a way that it is
possible to perform a three-way diff from initial http_ntlm.[ch] to resulting
http_ntlm.[ch] and curl_ntlm.[ch] to actually verify that no functional change
is introduced here.

Notice that Steve Holme has provided several patches, but these included this
refactoring along with 'extra' fixes. I really wanted this 'clean' refactoring
done first, in order to allow discussion or committing of 'extra' fixes on a
case by case basis, so, I had to bite the bullet ;-)

Comments, line adjustments, compiler warning fixes, whatever, may follow
afterwards.

warning C4706: assignment within conditional expression

Remove CURLntlm enum, no longer required.

Just a note about the fact that all VC[6/8/9/10] makefiles are generated
from the VC6 one as source.

Curl_readrewind() was called without checking its return code, which
could lead to badness.

Bug: http://curl.haxx.se/bug/view.cgi?id=3349227

Use preprocessor symbol NTLM_BUFSIZE to define private NTLM buffer fixed size.

Use a SessionHandle 'data' pointer variable to ease refactoring.

Update NTLM type-* message structure descriptions.

Fix some more spacing and typos (Steve Holme).

Moved NTLMSSP_SIGNATURE, HOSTNAME_MAX, SHORTPAIR and LONGQUARTET definitions in ready for move to curl_ntlm.c.

Used separate variables for Windows SSPI and native code to ease moving of code to curl_ntlm.c.

Fixed typographical erros where SPPI should be SSPI.

Fixed compilation warnings on 64-bit builds when calling Windows SSPI functions.

There are two keywords in cookie headers that don't follow the regular
name=value style: secure and httponly. Still we must support that they
are written like 'secure=' and then treat them as if they were written
'secure'. Test case 31 was much extended by Rob Ward to test this.

A regression where CURLFORM_BUFFER stopped to properly insert the file
name part in the formpart. Bug introduced in commit f851f768.

Added CURLFORM_BUFFER use to test 554 to verify this.

lwIP library initialization.

Use swrite/sread instead of write/read to avoid SIGPIPE

Allow configure builds to generate src/config-win32.h

Skip checksrc on src/config-win32.h contents already checked at lib/config-win32.h

Allow multiple -W in checksrc.pl

maketgz and buildconf.bat updated to reflect this.

A proxy could be marked 'httpproxy' wrongly before if set with an
environment variable or with the CURLOPT_PROXY option with a socks*://
prefix or similar.

Added test 710 to verify

Bug: http://curl.haxx.se/mail/lib-2011-07/0194.html

Allow compilation of libcurl and curl using BSD-style lwIP on Win32.

In order to compile libcurl and curl with this support it is necessary
to edit files lib/config-win32.h and src/config-win32.h and uncomment
a line to make definition of preprocessor symbol USE_LWIPSOCK visible.

Afterwards you can compile as usual.

In order to use compiled library with BSD-style lwIP TCP/IP stack in
your program it is mandatory that you include lwIP header file <lwip/opt.h>
before including <curl/curl.h> or <curl/multi.h>

Compilation has been verified with lwIP 1.4.0 and contrib-1.4.0 from:

http://download.savannah.gnu.org/releases/lwip/lwip-1.4.0.zip
http://download.savannah.gnu.org/releases/lwip/contrib-1.4.0.zip

Have fun!

... to avoid build failure when GSS_C_DELEG_POLICY_FLAG is not defined.
