    Now that all "blkcipher" algorithms have been converted to "skcipher",
    remove the blkcipher algorithm type.

    The skcipher (symmetric key cipher) algorithm type was introduced a few
    years ago to replace both blkcipher and ablkcipher (synchronous and
    asynchronous block cipher). The advantages of skcipher include:

    - A much less confusing name, since none of these algorithm types have
    ever actually been for raw block ciphers, but rather for all
    length-preserving encryption modes including block cipher modes of
    operation, stream ciphers, and other length-preserving modes.

    - It unified blkcipher and ablkcipher into a single algorithm type
    which supports both synchronous and asynchronous implementations.
    Note, blkcipher already operated only on scatterlists, so the fact
    that skcipher does too isn't a regression in functionality.

    - Better type safety by using struct skcipher_alg, struct
    crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc.

    - It sometimes simplifies the implementations of algorithms.

    Also, the blkcipher API was no longer being tested.

    crypto_has_ablkcipher() has no users, and it does the same thing as
    crypto_has_skcipher() anyway. So remove it. This also removes the last
    user of crypto_skcipher_type() and crypto_skcipher_mask(), so remove
    those too.
