    build: Add Common Autotools Module for MSVC Projects
    
    This adds a common autotools module that can be used by various projects to
    generate the Visual Studio projects as needed, and if necessary, generate
    the headers listings to "install" for that project, based on items passed
    in to this.  This is modelled on the Makefile.introspection autotools file
    that is used by many GNOME projects to generate the introspection files.
