In places the "host name" and "realm" variable was referred to as
"instance" whilst in others it was referred to as "host".

Turns out HMAC_Init is now deprecated in openssl master (and I spelled
HMAC_Init_ex wrong in previous commit)

Set HAVE_DES_SET_ODD_PARITY when using OpenSSL/BoringSSL as native
Windows builds don't use the autoconf tools.

curl_ntlm_core.c:150: warning 'Curl_des_set_odd_parity' undefined;
                      assuming extern returning int

But kept the original author, when they were specified in a comment, as
the initial copyright holder.

Put braces around empty "if" body in libcurl.m4 check to avoid warning:

        suggest braces around empty body in an 'if' statement

and make it work with -Werror builds.

Closes #402

Closes #398

remove redundant '}'

Closes #399

It isn't always clear to the user which options that cause the HTTP
methods to conflict so by spelling them out it should hopefully be
easier to understand why curl complains.

Closes #395

... since HTTP is forbidden to return any such.

This patch addresses known bug #76, where on 64-bit Windows SOCKET is 64
bits wide, but long is only 32, making CURLINFO_LASTSOCKET unreliable.

- Add new option CURLOPT_DEFAULT_PROTOCOL to allow specifying a default
protocol for schemeless URLs.

- Add new tool option --proto-default to expose
CURLOPT_DEFAULT_PROTOCOL.

In the case of schemeless URLs libcurl will behave in this way:

When the option is used libcurl will use the supplied default.

When the option is not used, libcurl will follow its usual plan of
guessing from the hostname and falling back to 'http'.

... so improve the #ifdefs for using our local implementation.

Since boringssl brought back DES_set_odd_parity again, it cannot be used
to differentiate from boringssl. Using the OPENSSL_IS_BORINGSSL define
seems better anyway.

Closes #393

... since boringssl moved the former ones and the check started to fail.

If strict certificate checking is disabled (CURLOPT_SSL_VERIFYPEER
and CURLOPT_SSL_VERIFYHOST are disabled) do not fail if the server
doesn't present a certificate at all.

Closes #392

The multi state machine would otherwise go into the DO_MORE state after
DO, even for the case when the FTP state machine had already performed
those duties, which caused libcurl to get stuck in that state and fail
miserably. This occured for for active ftp uploads.

Visual Studio complains with a message box:

"Run-Time Check Failure #1 - A cast to a smaller data type has caused a
loss of data.  If this was intentional, you should mask the source of
the cast with the appropriate bitmask.

For example:
char c = (i & 0xFF);

Changing the code in this way will not affect the quality of the
resulting optimized code."

This is because only 'val' is cast to unsigned char, so the "& 0xff" has
no effect.

Closes #387

- Clarify that FILE and SCP are disabled by default since 7.19.4
- Add that SMB and SMBS are disabled by default since 7.40.0
- Add CURLPROTO_SMBS to the list of protocols
