BGE cleanup: KX_GameObject::GetParent() no longer increases the object's
refcount.
I'm not sure why this function ever increased the object's refcount. Any
place in the code that calls KX_GameObject::GetParent() has to turn
around and call parent->Release(). Forgetting to call Release() was a
common cause of memory leaks (in fact, KX_SteeringActuator was probably
leaking). If the refcount needs to be increased, the calling code can
handle calling AddRef().
