* generator/CallbackGen.cs: Generate wrappers to map
	from managed delegates to native ones.
	* generator/Ctor.cs: Call parms.Initialize for the static case.
	* generator/Parameters.cs: Add "CType" property. Append []
	to CSType if necessary. Add "HideData" property if a container
	wishes to hide the user_data (used in callbacks).
	(Initialize): Add case for callback.
	* generator/SymbolTable.cs: Add size_t.

	* glue/program.c: string[] marshalling is no longer broken,
	remove hack.

	* sources/Gtk.metadata: Disable
	GtkColorSelection.SetChangePaletteHook and
	GtkTreeView.GetSearchEqualFunc for now, they return delegates and
	we don't support native->managed delegate mapping yet.
