[CRYPTO] cipher: Added block ciphers for CBC/ECB
This patch adds two block cipher algorithms, CBC and ECB. These are implemented as templates on top of existing single-block cipher algorithms. They invoke the single-block cipher through the new encrypt_one/decrypt_one interface. This also optimises the in-place encryption and decryption to remove the cost of an IV copy each round.
