From 861f7626f7da706f339a901b351e4398597a383d Mon Sep 17 00:00:00 2001
From: "Todd C. Miller" <millert@cvs.openbsd.org>
Date: Wed, 28 Apr 2004 16:52:09 +0000
Subject: Rename members of struct MD5Context to match other hash routines. Add
 constants for buffer lengths and use them. Make bit count 64bit based on
 changes by niklas@ long ago. Conver htole32n() to macros and unroll loops.
