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 .
