Herbert Xu da7f033ddc crypto: cryptomgr - Add test infrastructure
This patch moves the newly created alg_test infrastructure into
cryptomgr.  This shall allow us to use it for testing at algorithm
registrations.

Austin Zhang 8cb51ba8e0 crypto: crc32c - Use Intel CRC32 instruction
From NHM processor onward, Intel processors can support hardware accelerated
CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set.
The patch detects the availability of the feature, and chooses the most proper
way to calculate CRC32c checksum.
Byte code instructions are used for compiler compatibility.
No MMX / XMM registers is involved in the implementation.

Herbert Xu 5773a3e6e3 crypto: crc32c - Add ahash implementation
This patch reimplements crc32c using the ahash interface.  This
allows one tfm to be used by an unlimited number of users provided
that they all use the same key (which all current crc32c users do).

Neil Horman b8454eebe3 crypto: prng - Deterministic CPRNG
This patch adds a cryptographic pseudo-random number generator
based on CTR(AES-128).  It is meant to be used in cases where a
deterministic CPRNG is required.

One of the first applications will be as an input in the IPsec IV
generation process.

Building latest git fails with the following error:

This appears to happen because CONFIG_CRYPTO_TEST is set while
CONFIG_CRYPTO_BLKCIPHER is not.

Herbert Xu 653ebd9c85 [CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/module
With the impending addition of the givcipher type, both blkcipher and
ablkcipher algorithms will use it to create givcipher objects.  As such
it no longer makes sense to split the system between ablkcipher and
blkcipher.  In particular, both ablkcipher.c and blkcipher.c would need
to use the givcipher type which has to reside in ablkcipher.c since it
shares much code with it.

This patch merges the two Kconfig options as well as the modules into one.
