From: Lev Stipakov <lev@openvpn.net>

Add manifest file to detect Windows versions greater than Windows 8.

Below is example output on Windows 10.

Before:
        Windows version 6.2 (Windows 8 or greater) 64bit

After:
        Windows version 10.0 (Windows 10 or greater) 64bit

 v2: 
     - fix build from tarball (added manifest file to EXTRA_DIST)
     - fix build on old mingw like ubuntu 18.04 (added missig define)

Thanks for the v2.  Builds nicely with "./build-snapshot" on my 
ubuntu 18.04 builder now.  I have not tested the resulting installer.

The code change for the C code look good to me.

Thanks for the explanation about the manifest ("I've heard that 
before, but I won't ever become a windows programmer, it seems"),
and I assume that the .vcproj adaptions are related to that.

You are the expert on MSVC building, so if you say this is needed,
and it does not look harmful, I'm fine :-)

Your patch has been applied to the master branch.
