Ard Biesheuvel d63007eb95 crypto: ablkcipher - remove deprecated and unused ablkcipher support
Now that all users of the deprecated ablkcipher interface have been
moved to the skcipher interface, ablkcipher is no longer used and
can be removed.

Eric Biggers c65058b758 crypto: skcipher - remove the "blkcipher" algorithm type
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.

Eric Biggers cec0cb8a28 crypto: skcipher - remove crypto_has_ablkcipher()
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.

The :functions: definition allows the specification of multiple
function references which prevents parsing the header file multiple

Stephan Mueller 3b72c814a8 crypto: doc - convert crypto API documentation to Sphinx
With the conversion of the kernel crypto API DocBook to Sphinx, the
monolithic document is broken up into individual documents. The
documentation is unchanged with the exception of a slight reordering to
keep the individual document parts self-contained.
