use when the IntPtr is NULL.
* generator/SignalHandler.cs, generator/CallbackGen.cs: removed
call to Initialize for structs
* gtk/Clipboard.custom, gtk/ClipboardClearFunc.cs,
gtk/ClipboardGetFunc.cs,
gtk/GtkSharp.GtkClipboardClearFuncNative.cs,
gtk/GtkSharp.ClipboardGetFuncNative.cs, SelectionData.custom:
Hand-wrapped selection handling stuff, along with relevant
signals and the like.
* gnome/voidObjectAffineSVPintSignal.cs: removed Initialize
for hand-wrapped signal
* sample/GnomeHelloWorld.cs, sample/Size.cs: compare against
.Zero instead of using IsNull

hiding some manually-wrapped stuff
svn path=/trunk/gtk-sharp/; revision=8912
* glib/Object.cs (Ref): Added.
* gtk/Object.custom (Ref): Overload. Note that we were reffed.
(DisposeNative): Unref if we were explicitly reffed.
* generator/Method.cs: Call Ref if needs_ret is set.
* generator/StructBase.cs: Call Ref on all object accessors.
* glue/style.c: Ref returned GCs.
* sources/Gtk.metadata: Set needs_ret on various gdk-related
accessors in GtkWidget. Hide Ref/Unref methods on Widget and
RcStyle as these ought to be deprecated anyway.
