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

Fixed:
293 - from http://bugzilla.redhat.com/723075 "curl segfaults"

When using both -J and a single -O with multiple URLs, a missing init
could cause badness.

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!

Closed this entry:
290 - bug 3375603 "curl has problem with remote names containing ';'"

Content-disposition headers can provide file names with semicolons which
previously would be cut off at that point.

Added test case 1311 and 1312 to verify -J.

Use preprocessor symbols WINBIND_NTLM_AUTH_ENABLED and WINBIND_NTLM_AUTH_FILE
for Samba's winbind daemon ntlm_auth helper code implementation and filename.

Retain preprocessor symbol USE_NTLM_SSO for NTLM single-sign-on feature
availability implementation independent.

For test harness, prefix NTLM_AUTH environment vars with CURL_

Refactor and rename configure option --with-ntlm-auth to --enable-wb-ntlm-auth[=FILE]

The 20xx range is for multiple sequential tests.

This reverts commit bc6e6a46.

Initialize variables when connectdata object is created.

Defining NCOMPAT eliminates the backwards-compatibility macros
that are the source of the problem and which we don't need,
anyway.

Fix compiler warning

This caused fake_ntlm to abort due to an invalid command
causing sporadic test 2005 failures.

Enhance test harness fake_ntlm logging upon invalid input.
