    [TRAFODION-2228]Add AES_ENCRYPT/AES_DECRYPT functions

    Add two functions which used to encrypt and decrypt the data using the
      official AES (Advanced Encryption Standard) algorithm.
    AES_ENCRYPT(str, key_str[, init_vector])
    AES_DECRYPT(crypt_str, key_str[, init_vector])
    
    Both these two function have optional init_vector argument which
    provides an initalization vector for block encryption modes that
    require it. For modes that require the optional init_vector argument, an error
    occurs if init_vector is missing. For modes that don't need
    init_vector, it will raise a unused argument waring if init_vector is
    provided.
    
    The new CQD block_encryption_mode controls the mode for
    block-based
    encryption algorithm. The default value is 0, which use
    aes-128-ecb.
    
    Here is the list for diffferent values for
    block_encryption_mode
    
    CQD value          algorithm
    0             aes-128-ecb
    1             aes_192_ecb
    2             aes_256_ecb
    3             aes_128_cbc
    4             aes_192_cbc
    5             aes_256_cbc
    6             aes_128_cfb1
    7             aes_192_cfb1
    8             aes_256_cfb1
    9             aes_128_cfb8
    10            aes_192_cfb8
    11            aes_256_cfb8
    12            aes_128_cfb128
    13            aes_192_cfb128
    14            aes_256_cfb128
    15            aes_128_ofb
