    Visual Studio builds: Add support for Visual Studio 2017
    
    This adds support for Visual Studio 2017 projects by using the new
    win32/Makefile-newvs.am that was updated from the last commit, so that
    the 2010 projects can be copied and updated accordingly for the 2017
    projects.
    
    Note that the format of the toolset version string changed for Visual
    Studio 2017, so allow and use a custom toolset version string when
    specified, otherwise generate it as it was before.
    
    Note also that Visual Studio 2017 aims to be compatible with Visual Studio
    2015 on the CRT level, so one should be able to use 2017-compiled binaries
    with 2015-compiled binaries without problems.
