Add AES-CCM encryption, and plumb into OCF. This commit essentially has three parts: * Add the AES-CCM encryption hooks. This is in and of itself fairly small, as there is only a small difference between CCM and the other ICM-based algorithms. * Hook the code into the OpenCrypto framework. This is the bulk of the changes, as the algorithm type has to be checked for, and the differences between it and GCM dealt with. * Update the cryptocheck tool to be aware of it. This is invaluable for confirming that the code works. This is a software-only implementation, meaning that the performance is very low. Sponsored by: iXsystems Inc.

OCF: Add plain hash modes In part, to support OpenSSL's use of cryptodev, which puts the HMAC pieces in software and only offloads the raw hash primitive. The following cryptodev identifiers are added: * CRYPTO_RIPEMD160 (not hooked up) * CRYPTO_SHA2_224 * CRYPTO_SHA2_256 * CRYPTO_SHA2_384 * CRYPTO_SHA2_512 The plain SHA1 and 2 hashes are plumbed through cryptodev (feels like there is a lot of redundancy here...) and cryptosoft. This adds new auth_hash implementations for the plain hashes, as well as SHA1 (which had a cryptodev.h identifier, but no implementation). Add plain SHA 1 and 2 hash tests to the cryptocheck tool. Motivation stems from John Baldwin's earlier OCF email, https://lists.freebsd.org/pipermail/freebsd-arch/2018-January/018835.html .

Import Blake2 algorithms (blake2b, blake2s) from libb2 The upstream repository is on github BLAKE2/libb2. Files landed in sys/contrib/libb2 are the unmodified upstream files, except for one difference: secure_zero_memory's contents have been replaced with explicit_bzero() only because the previous implementation broke powerpc link. Preferential use of explicit_bzero() is in progress upstream, so it is anticipated we will be able to drop this diff in the future. sys/crypto/blake2 contains the source files needed to port libb2 to our build system, a wrapped (limited) variant of the algorithm to match the API of our auth_transform softcrypto abstraction, incorporation into the Open Crypto Framework (OCF) cryptosoft(4) driver, as well as an x86 SSE/AVX accelerated OCF driver, blake2(4). Optimized variants of blake2 are compiled for a number of x86 machines (anything from SSE2 to AVX + XOP). On those machines, FPU context will need to be explicitly saved before using blake2(4)-provided algorithms directly. Use via cryptodev / OCF saves FPU state automatically, and use via the auth_transform softcrypto abstraction does not use FPU. The intent of the OCF driver is mostly to enable testing in userspace via /dev/crypto. ATF tests are added with published KAT test vectors to validate correctness.

Add xform-conforming auth_hash wrapper for Poly-1305 The wrapper is a thin shim around libsodium's Poly-1305 implementation. For now, we just use the C algorithm and do not attempt to build the SSE-optimized variant for x86 processors. The algorithm support has not yet been plumbed through cryptodev, or added to cryptosoft.
