Commit 7a09b52c

 introduced support
for the draft-ietf-httpbis-cookie-alone-01 cookie draft, and while
the entry was removed from the TODO it was mistakenly left here.
Fix by removing and rewording the entry slightly.

- Use explicit include opt for perl calls.

Prior to this change some scripts couldn't find their dependencies.

At the top, perl is called using with the "-Isrcdir" option, and it
works:

https://github.com/curl/curl/blob/curl-7_63_0/tests/runtests.pl#L183

But on line 3868, that option is omitted. This caused problems for me,
as the symbol-scan.pl script in particular couldn't find its
dependencies properly:

https://github.com/curl/curl/blob/curl-7_63_0/tests/runtests.pl#L3868

This patch fixes that oversight by making calls to perl sub-shells
uniform.

Closes https://github.com/curl/curl/pull/3496

If the incoming len 5, but the buffer does not have a termination
after 5 bytes, the strtol() call may keep reading through the line
buffer until is exceeds its boundary. Fix by ensuring that we are
using a bounded read with a temporary buffer on the stack.

CVE-2018-16890

Attempt to add support for Secure Channel binding when negotiate
authentication is used. The problem to solve is that by default IIS
accepts channel binding and curl doesn't utilise them. The result was a
401 response. Scope affects only the Schannel(winssl)-SSPI combination.

Fixes https://github.com/curl/curl/issues/3503
Closes https://github.com/curl/curl/pull/3509

Stick to "Schannel" everywhere. The configure option --with-winssl is
kept to allow existing builds to work but --with-schannel is added as an
alias.

Use an ephemeral port number here; previously the example had 8080
which could be confusing as the common web server port number might
be misinterpreted as suggesting this option affects the remote port.

A backslash should be escaped in Roff / Troff.

By default WinSSL selects and send a client certificate automatically,
but for privacy and consistency we should offer an option to disable the
default auto-send behavior.

Compiling with msvc /analyze and a recent Windows SDK warns against
using GetTickCount (Suggests to use GetTickCount64 instead.)

Since GetTickCount is only being used when GetTickCount64 isn't
available, I am disabling that warning.

CURLOPT_SSH_KNOWNHOSTS and CURLOPT_SSH_KEYFUNCTION are supported for
libssh as well. So accepting these options only when compiling with
libssh2 is wrong here.

Fixes #3493
Closes #3494

By default, libssh creates a new socket, instead of using the socket
created by curl for SSH connections.

Pass the socket created by curl to libssh using ssh_options_set() with
SSH_OPTIONS_FD directly after ssh_new(). So libssh uses our socket
instead of creating a new one.

This approach is very similar to what is done in the libssh2 code, where
the socket created by curl is passed to libssh2 when
libssh2_session_startup() is called.
