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.

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!

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]

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.

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

Fix compiler warning

Provide some error tracing and fix execl() calling.

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.

Bug: http://curl.haxx.se/bug/view.cgi?id=3370895

When libcurl has said to the server that there's a POST or PUT coming
(with a content-length and all) it has to either deliver that amount of
data or it needs to close the connection before trying a second request.

Adds test case 1129, 1130 and 1131

The bug report is about when used with 100-continue, but the change is
more generic.

gssapi.h is used as a header name by Heimdal-style GSSAPI so it would
conflict with a private header using that name, and while renaming the
header I figured we should name the .c file accordingly as well.

Modern gcc versions (4.6.X) get more picky by default and have started
to warn for unused parameters, but luckily gcc also allows us to mark
them as unused so that we can avoid the warnings.

Removed the parameters that were common to all our invocation.

This function wraps our calls to gss_init_sec_context so that we
have a unified way to talk to GSSAPI.

This change makes this callsite match the rest of the code.

We use "if(condition) {" with a space between the close paren and the
open brace.

Previously it would access a NULL pointer and die.

This is a security flaw. See curl advisory 20110623 for details.
