With authentication support some nodes (master node, super block node) get a HMAC embedded into them. This patch adds functions to prepare and write such a node. The difficulty is that besides the HMAC the nodes also have a CRC which must stay valid. This means we first have to initialize all fields in the node, then calculate the HMAC (not covering the CRC) and finally calculate the CRC.
