[Openvpn-devel,v2] msvc: OpenSSL 1.1.x support

  Since we release Windows client with OpenSSL 1.1.0
(and will switch to 1.1.1 in the next release),
it makes sense to use a newer version in VS build.

This patch adds msvc-specific defines which imply
that underlying OpenSSL is 1.1.x (works with 1.1.0 and 1.1.1).

Also OpenSSL library names in project file are updated.

v2: clarify in comment and commit message that
    this supports 1.1.x, which is 1.1.0 and 1.1.1.

Hi,

Unfortunately, I have no Visual Studio 2017 available any more. So, I had to upgrade the openvpn-build and openvpn to build with VS2019 first.

Tested with OpenSSL 1.1.1d and this patch is indeed required to build openvpn.exe.

Best regards,
Simon

Your patch has been applied to the master branch.

(I have not done more than "see that there are no code changes involved"
- if Simon and you say the build system changes are fine, I just believe so)
