As in the version in of this NMake Makefile module in G-I, support
CFG == Release|Debug, which is what is used in the Visual Studio
projects, so that:
-This file will be in sync with the one in G-I
-Other projects that make use of this can integrate this NMake Makefile
module in their Visual Studio project files.
Update this common NMake Makefile module so projects using this (such as
for introspection builds or projects supporting MSVC builds using NMake)
can make use of Visual Studio 2017.
This adds support for Visual Studio 2017 by updating the autotools files for
copying and updating the Visual Studio 2010 project files.
Since the toolset version of Visual Studio 2017 is no longer in the form
of $(MSVC_VER_SHORT)0, we need to specify the full number, but this is a
rather simple change we have here. Note that Visual Studio 2017's CRT
aims to be compatible with the 2015's CRT, so it should be possible to
use 2017-compiled code with the 2015-compiled ones.
It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
