* generator/CallbackGen.cs : switch to NativeCallbackSignature.
	* generator/GenBase.cs : add NativeCallbackType member.
	* generator/IGeneratable.cs : add NativeCallbackType member.
	* generator/ManagedCallString.cs : add guarded post call struct
	marshaling back to the native struct.
	* generator/NativeCallbackSignature.cs : new parallel to ImportSignature
	but using NativeCallbackType instead of MarshalType.
	* generator/Signal.cs : switch vm and sig marshaler callbacks to 
	NativeCallbackSignature. Perform guarding post call struct marshaling
	back to the native struct.
	* generator/Parameters.cs : add NativeCallbackType member.
	* generator/SimpleBase.cs : add NativeCallbackType member.
	* generator/StructBase.cs : add NativeCallbackType member using IntPtr
	to support NULL handling.
	* gtk/NodeCellDataFunc.cs : update native marshaler sig.
