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 modeled on the Makefile.introspection autotools file
that is used by many GNOME projects to generate the introspection files.
