[Rework of a patch from Ben Maurer to turn GLib.Value
	into a valuetype.]
	* generator/BoxedGen.cs : fix operators for new valuetype GValues.
	* generator/ByRefGen.cs : new generatable for byref value types.
	* generator/Makefile.am : add ByRefGen.cs.
	* generator/MethodBody.cs : remove GValue special casing.
	* generator/Property.cs : rework value handling.
	* generator/Signal.cs : fix base virtual method value passing.
	* generator/SymbolTable.cs : map GValue to ByRefGen.
	* glib/Object.cs : rework GetProperty and SetProperty.
	* glib/Value.cs : make it a value type.
	* glib/ValueArray.cs : fix GValue passing.
	* glib/glue/value.c : rework for valuetype GValues.
	* gnome/Program.custom : fix GValue passing
	* gtk/Gtk.metadata : make TreeModel.GetValue value param pass_as=ref.
	* gtk/ListStore.custom : fix GValue passing
	* gtk/NodeStore.cs : fix GValue passing
	* gtk/TextTag.custom : fix GValue passing
	* gtk/TreeModelSort.custom : fix GValue passing
	* gtk/TreeStore.custom : fix GValue passing
