This patch removes the old crypto_grab_skcipher helper and replaces
it with crypto_grab_skcipher2.
As this is the final entry point into givcipher this patch also
removes all traces of the top-level givcipher interface, including
all implicit IV generators such as chainiv.
The bottom-level givcipher interface remains until the drivers
using it are converted.

As there are no more kernel users of built-in IV generators we
can remove the special lookup for skciphers.

This patch converts cts over to the skcipher interface. It also
optimises the implementation to use one CBC operation for all but
the last block, which is then processed separately.

This patch adds an skcipher null object alongside the existing
null blkcipher so that IV generators using it can switch over
to skcipher.

This patch converts chacha20poly1305 to use the new skcipher
interface as opposed to ablkcipher.
It also fixes a buglet where we may end up with an async poly1305
when the user asks for a async algorithm. This shouldn't be a
problem yet as there aren't any async implementations of poly1305
out there.

This patch converts authencesn to use the new skcipher interface as
opposed to ablkcipher.
It also fixes a little bug where if a sync version of authencesn
is requested we may still end up using an async ahash. This should
have no effect as none of the authencesn users can request for a
sync authencesn.

This patch adds a chunk size parameter to aead algorithms, just
like the chunk size for skcipher algorithms.
However, unlike skcipher we do not currently export this to AEAD
users. It is only meant to be used by AEAD implementors for now.

Current the default null skcipher is actually a crypto_blkcipher.
This patch creates a synchronous crypto_skcipher version of the
null cipher which unfortunately has to settle for the name skcipher2.

This patch allows skcipher algorithms and instances to be created
and registered with the crypto API. They are accessible through
the top-level skcipher interface, along with ablkcipher/blkcipher
algorithms and instances.
This patch also introduces a new parameter called chunk size
which is meant for ciphers such as CTR and CTS which ostensibly
can handle arbitrary lengths, but still behave like block ciphers
in that you can only process a partial block at the very end.
For these ciphers the block size will continue to be set to 1
as it is now while the chunk size will be set to the underlying
block size.

for condition comparison and cleanup multiline comment style
In sha*_ctx_mgr_submit, we currently use the | operator instead of ||
((ctx->partial_block_buffer_length) | (len < SHA1_BLOCK_SIZE))
Switching it to || and remove extraneous paranthesis to
adhere to coding style.
Also cleanup inconsistent multiline comment style.
