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.

Fix compiler warning

Provide some error tracing and fix execl() calling.

Ensure test harness fake_ntlm main function can properly handle arguments.

Use fake_ntlm absolute filename in NTLM_AUTH environment variable for test
2005 definition.

Also, set the test number in the test data file so fake_ntlm can
be reused in future tests.

When an easy handle is used to download an URI which has no
Content-Length header (or equivalent) after downloading an URI which
does, the value from the previous transfer is reused and returned by
CURLINFO_CONTENT_LENGTH_DOWNLOAD. This is because the progress flags
(used to determine whether such a header was received) are not reset
between transfers.
