    dm_target_crypt_ng - Improve crypto_cipher API
    
    * Introduce sessions - crypto_cipher_initsession() and
      crypto_cipher_freesession().
    
    * This allows us to hide (most) implementation details.
    
    * Expose public functions `crypto_cipher_` instead of calling the
      function pointers from crypto_cipher directly. Required to hide
      implementation details.
    
    * Move error checking into the API layer. Cipher implementations can
      assume that the context is correctly memory aligned and the block
      size matches that of the algorithm.
