win: support for Visual Studio 2017

This patch enables building openvpn with Visual Studio 2017. It is advised to use openvpn-build/msvs/build.bat which also downloads and build required dependencies. Changes made: - updated path to Visual Studio toolchain - updated platform toolset - added missing libraries - added x64 configurations - enabled AEAD ciphers to make NCP work - enabled unicode support - updated source files in project settings - fix includes - restored variable which was erroneously removed - added properties file which sets required env variables (required to build with IDE) - etc Signed-off-by: Lev Stipakov <lev@openvpn.net> Acked-by: Simon Rozman <simon@rozman.si> Message-Id: <1538141209-32330-1-git-send-email-lstipakov@gmail.com> URL: https://www.mail-archive.com/openvpn-devel@lists.sourceforge.net/msg17499.html Signed-off-by: Gert Doering <gert@greenie.muc.de>
