Add enum GdkModifierIntent which identifies use cases for modifier masks and GdkKeyMap::get_modifier_mask(). Add a default implementation which returns what is currently hardcoded all over GTK+, and an implementation in the quartz backend. Also add gtk_widget_get_modifier_mask() which simplifies things by doing widget->display->keymap->get_modifier_mask().
