Merge r1862611, r1877693, r1878703, r1884207 from trunk:

* support/htpasswd.c (usage): Document SHA-256/512 support.

Windows : do not include ap_config_auto.h

* support/htpasswd.c (usage): Fix typo.

Fix misleading crypt vs hash terminology in ht* and dbmmanage tools.

What the htpasswd, htdbm and dbmmanage tools do is hashing passwords, not
encrypting them, so fix the terminology in manpages, docs, --help, comments
and function names.
