    Drop AES functions and pycrypto dependency

    At some point IV parameter has been removed making these functions
    dangerous to use unless keys are unique on every message. Since the
    functions were added the original consumer has disappeared too. With
    no more users it's better to get rid of the incomplete encryption system
    entirely.

    These were the only functions using pycrypto module directly, so it was
    also removed from the dependency list.

    Fixes bug: 1033178
