Replace SHA256 implementation with one from LibreSSL
They have cleaner code than OpenSSL :) from here: https://github.com/libressl/openbsd/tree/master/src/lib/libcrypto and https://github.com/libressl/portable

* Obligatory macros:

* DATA_ORDER_IS_BIG_ENDIAN or DATA_ORDER_IS_LITTLE_ENDIAN
|

* HASH_LONG_LOG2 *has to* be defined along
|

* HASH_CTX
