    Build: Add rsvg.symbols File to Export Public Symbols
    
    This adds a rsvg.symbols file that can be preprocessed to create the
    .def file for exporting the symbols (functions) from the librsvg DLL.
    
    I do understand that there is a maintenance overhead with this, and
    this is the former way that symbol exporting was done in GLib and
    GTK+, but this is done as we are now in a stable release series,
    where we can use a __declspec(dllexport) (a.k.a visibility-based
    export mechanism) if we want in the next dev cycle.
