- Update VS project templates to use the OpenSSL lib names and include
  directories for OpenSSL 1.1.x.

This change means the VS project files will now build only with OpenSSL
1.1.x when an OpenSSL configuration is chosen. Prior to this change the
project files built only with OpenSSL 1.0.x (end-of-life) when an
OpenSSL configuration was chosen.

The template changes in this commit were made by script:

libeay32.lib => libcrypto.lib
ssleay32.lib => libssl.lib
..\..\..\..\..\openssl\inc32 => ..\..\..\..\..\openssl\include

And since the output directory now contains the includes it's prepended:
..\..\..\..\..\openssl\build\Win{32,64}\VC{6..15}\{DLL,LIB}
{Debug,Release}\include

- Change build-openssl.bat to copy the build's include directory to the
  output directory (as seen above).

Each build has its own opensslconf.h which is different so we can't just
include the source include directory any longer.

Note the include directory in the output directory is a full copy from
the build so technically we don't need to include the OpenSSL source
include directory in the template. However, I left it last in case the
user made a custom OpenSSL build using the old method which would put
opensslconf in the OpenSSL source include directory.

- Change build-openssl.bat to use a temporary install directory that is
  different from the temporary build directory.

For OpenSSL 1.1.x the temporary paths must be separate not a descendant
of the other, otherwise pdb files will be lost between builds.

Windows project configurations that use OpenSSL with USE_WIN32_CRYPTO
need crypt32.

- Generate VQUIC and VSSH filenames in Visual Studio project files.

Prior to this change generated Visual Studio project configurations that
enabled SSH did not build properly. Broken since SSH files were moved to
lib/vssh 3 months ago in 5b2d703.

- s/USE_CYASSL/USE_WOLFSSL/

- Remove old compatibility macros.

Follow-up to 1c6c59a from several months ago when CyaSSL named symbols
were renamed to wolfSSL. The wolfSSL library was formerly named CyaSSL
and we kept using their old name for compatibility reasons, until
earlier this year.

All Windows APIs have been natively UTF-16 since Windows 2000 and the
non-Unicode variants are just wrappers around them. Only Windows 9x
doesn't understand Unicode without the UnicoWS DLL. As later Visual
Studio versions cannot target Windows 9x anyway, using the ANSI API
doesn't really have any benefit there.

This avoids issues like KNOWN_BUGS 6.5.

Already done in commit d5cfefd0ea8e331b884186bff484210fad36e345 for the
library project, but I forgot the tool project template. Now also
removed for that.

Starting with Visual Studio 2017 Update 9, Visual Studio doesn't like
the MinimalRebuild option anymore and warns:

cl : Command line warning D9035: option 'Gm' has been deprecated and
will be removed in a future release

The option can be safely removed so that the default is used.

The Visual Studio builds didn't use IPv6. Add it to all projects since
Visual Studio 2008, which is verified to build via AppVeyor.

Closes https://github.com/curl/curl/pull/3137

Previously, they were opened with Visual Studio 2015 by default, which
cannot build them.
