GtkSharp/gtk/Input.custom
Dan Winship a7d8b64f7a * generator/Parameters.cs (Parameters.Validate): If the parameters
end with "callback, gpointer, GDestroyNotify", then mark the
	callback as having "notified" Scope.
	(Parameters.IsHidden): Hide user_data and GDestroyNotify after a
	callback.
	(Parameter.Scope): make this settable
	(Parameter.IsDestroyNotify): new test

	* generator/MethodBody.cs (Initialize): Handle "notified" callback
	scope (using a GCHandle and GLib.DestroyHelper.NotifyHandler)

	* generator/CallbackGen.cs (GenWrapper): Add a static
	"GetManagedDelegate" method to the wrapper type, to translate a
	native delegate back to its corresponding managed delegate.
	(FromNative): use GetManagedDelegate.

	* generator/ReturnValue.cs (Validate): We handle callback return
	values now

	* generator/SymbolTable.cs: marshal GDestroyNotify as
	GLib.DestroyNotify

	* glib/DestroyNotify.cs: Moved from gtk

	* gtk/Gtk.metadata: globally change GtkDestroyNotify to
	GDestroyNotify, but then change back the ones that are exposed in
	the API. Un-hide lots of methods we can correctly autogenerate
	now.

	* gtk/DestroyHelper.cs: moved to glib

	* gtk/*.custom: remove methods that are autogenerated now, add
	Obsolete wrappers where needed, replace Gtk.DestroyHelper usage
	with GLib.DestroyHelper.

	* gdk/Gdk.metadata: 
	* gnome/Gnome.metadata: Turn Gdk.Drawable.SetData and
	Gnome.IconList.SetIconDataFull's GDestroyNotify args into
	gpointers so the generated API stays the same as it used to be.

	* rsvg/Handle.custom: implement deprecated SetSizeCallback

	* sample/GtkDemo/DemoIconView.cs (CreateSort): update for API
	changes
