* generator/Parameters.cs: Allow nulls if null_ok set. * generator/SymbolTable.cs: Add method IsStruct. * parser/Gtk.metadata, Gdk.metadata, Gnome.metadata: Merge in null_ok from *.defs. This is probably incomplete though, I've already found one method that wasn't listed. * sample/GnomeHelloWorld.cs: Remove IntPtr.Zero hack. svn path=/trunk/gtk-sharp/; revision=5792
