Windows standard libraries are located in C:/Program Files/Microsoft
SDKs/[...]. They are already included in the default MSVC
LIBPATH. Hence, find_library(WSOCK32_LIBRARY wsock32) and
find_library(WS2_32_LIBRARY ws2_32) are not needed. They return the full
path to the libraries including spaces. Of course,
list_spaces_append_once will mangle the result and the build fails.

If the Curl_ipv6works() function says no, there is no reason to try AAAA
names even if libcurl was built with IPv6 support enabled.

Changed the returned curl error codes for EHLO and HELO responses from
CURLE_LOGIN_DENIED to CURLE_REMOTE_ACCESS_DENIED as a negative response
from these commands represents no service as opposed to a login error.

Since the host name is passed in to the cookie engine it will not work
correctly if the brackets are left in the name.

An alternative would be:

1. specify HTTPS_CA_DIR and/or HTTPS_CA_FILE
2. ensure that Net::SSL is being used, and IO::Socket::SSL is NOT being
   used

Curl_protocol_connect() now does the tunneling through the HTTP proxy if
requested instead of letting each protocol specific connection function
do it.

The check for Winsock definition was a bit too broad

In line with the manpage, curl-config --libs should only provide the necessary
library flags for the linker in order to compile software with libcurl. Also
with this change, we match what the pkg-config file provides.

Correct some inconsistencies in which version some things were added.

Commit 466150bc fixed the Host: header with CONNECT, but I then
forgot the preceeding request-line. Now this too uses [brackets]
properly if a ipv6 numerical address was given.

Set the conn->data->info.httpcode variable in smtp_statemach_act() to
allow Curl_getinfo() to return the SMTP response code via the
CURLINFO_RESPONSE_CODE action.

With Colin Hogben's recent work, --libcurl now also works with -F and
more. Remove the previous caveat.

The line endings broke when I saved the three recent patches (my fault,
not Colin's) to 'git am' them.

Adjusted the stripping of the test program for comparing to also exclude
the SSH key file name as that will differ and use a local path name.

The intention is to take the output of curl's --libcurl option,
as exercised in test 14xx, and generate a corresponding test15xx
in which the generated code is compiled and run.  This will verify
that the generated code behaves equivalently to the original
invocation of the curl command.

The script is not yet integrated into the configure / makefile
machinery.

These tests check the output of the --libcurl option of curl,
including the improved option handling added in a related patch.

This patch improves the output of curl's --libcurl option by
generating code which builds curl_httppost and curl_slist lists, and
uses symbolic names for enum and flag values.  Variants of the
my_setopt macro in tool_setopt.h are added in order to pass extra type
information to the code-generation step in tool_setopt.c.

If curl is configured with --disable-libcurl-option then the macros
call curl_easy_setopt directly.

Fixed a problem in smtp_done() when writing out the postdata as
Curl_write() would periodically return zero bytes written.

Brought in commit 0cf0ab6f

With commit 035ef06b applied, the test pop3 server needs to send
".\r\n" as the body terminating sequence and there needs to be a final
CRLF in the actual body in the test data file.

Curl_pop3_write() would drop the final CRLF of a message as it was
considered part of the EOB as opposed to part of the message. Whilst
the EOB sequence needs to be searched for by the function only the
final 3 characters should be removed as per RFC-1939 section 3.

Reported by: Rich Gray
Bug: http://curl.haxx.se/mail/lib-2012-02/0051.html

Curl_smtp_escape_eob() would leave off final CRLFs from emails ending
in multiple blank lines additionally leaving the smtpc->eob variable
with the character count in, which would cause problems for additional
emails when sent through multiple calls to curl_easy_perform() after a
CURLOPT_CONNECT_ONLY.

Make sure it is mentioned once and with the correct description
