Previously, we will store all nat version bitmap in checkpoint pack block, so our total node entry number has a limitation which caused total node number can not exceed (3900 * 8) block * 455 node/block = 14196000. So that once user wants to create more nodes in large size image, it becomes a bottleneck, that's unreasonable. This patch detects the new layout of nat/sit version bitmap in image in order to enable supporting large nat bitmap.
