Wed Mar 8 06:09:04 CST 2017
From: Michael Müller <michael at fds-team.de>
Based on public domain implementation from
https://git.musl-libc.org/cgit/musl/tree/src/crypt/crypt_sha512.c

Changes in v3:
* Use macro for 64-bit consts.
Replaces patch 4/5, the rest of the series is still valid.
Alexandre, feel free to pick which version you think is best. *g*
