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.

Three more bugs fixed, three more contributors mentioned

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

When building on Windows, with CMake and mingw, curl fails to compile
because the CMake build system is not properly looking for the Winsock
libraries

Patch by: Pau Garcia i Quiles
Bug: http://curl.haxx.se/bug/view.cgi?id=3389231

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

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

Using this option with an argument being set to one of
none/policy/always instructs libcurl how to deal with GSS
credentials. Or rather how it tells the server that delegation is fine
or not.

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.

Trimmed the newlines to be LF-only. Converted the source to plain C, to
use curl style indents, to compile warning-free with picky options and
fixed the minor fprintf() bug on line 245. Added to makefile.

15.8 remove 'curl_httppost' from public

289 - bug 3349227 "secure attribute in cookie does not work with equals sign"

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.

Reported by: "gnombat"

This is to aid easier machine parsing and to make sure nobody who reads
these header lines can miss the info.

Mention 5 bugixes and 1 change more

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.

Bug: http://curl.haxx.se/mail/lib-2011-07/0176.html
Reported by: Henry Ludemann

Add CURL_CHECK_COMPILER as a requirement.

Ensure macro does nothing unless GNU_C or CLANG compiler is used.

This should allow usage of this macro in unforeseen placements.

The connect timeout logic when using SOCKS was done wrong

When a failure has been detected we must abort immdiately.

Drop the pre-release part from this text as we don't use that in
practise since many years.

Update the phrasing to reflect our more strict interpretation:
