- 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.

Follow-up to 148534d which added CURLSSLOPT_NATIVE_CA for 7.71.0.

- 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.

Closes #854

After squashing most of our compiler warnings, up'ed the default
warning level from 3 to 4 in order to increase the likelyhood of
catching future warnings.

Updated the makefiles and Visual Studio project files to support moving
the authentication code to the new lib/vauth directory that was started
in commit 0d04e859e1.

In addition to commit 709cf76f6b, removed the USE_SSLEAY preprocessor
variable from the Visual Studio project files as it isn't required
anymore.

Defined the DEBUGBUILD pre-processor variable to allow extra logging,
which is particularly useful in debug builds, as we use this and Visual
Studio typically uses _DEBUG.

We could define DEBUBBUILD, in curl_setup.h, when _MSC_VER and _DEBUG is
defined but that would also affect the makefile based builds which we
probably don't want to do.

As this pre-processor definition is defined in curl_setup.h there is no
need to include it in the Visual Studio project files.
