* configure.in.in: add new dir and autofu for it. * Makefile.am: add new dir * gapi/*: a small extension method library to add generation-related api to GType in 2.0. Access it with -pkg:gapi-2.0-compat to pick up the needed refs. * generator/GObjectVM.cs: generate new GType getter methods. * generator/ObjectGen.cs: generate new GType getter methods. * glib/GType.cs: change a few props to methods to make them extension method friendly for 2.0 compat. * glib/Object.cs: use new GType getter methods. * glib/Value.cs: use new GType getter methods. * gtk/Widget.custom: use new GetClassPtr method. svn path=/trunk/gtk-sharp/; revision=139609
