Enhance the authentication password handling so that stored
	passwords can be encrypted with either DES or MD5.  htpasswd can
	now generate either on systems that allow both, and MD5 on
	Win32.   .htpasswd files can contain both types; usernames
	with passwords encrypted with MD5 and usernames with DES
	passwords can appear in the same file.  The authentication
	modules (mod_auth, mod_auth_db, mod_auth_dbm) autosense the
	correct algorithm from the stored password.

	This gives us encrypted passwords on Win32 at last.  This is
	only the first part of the patch; some changes to allow the
	Win32 side to build properly are being fixed and should be
	committed to-morrow.  However, Unix systems can build with
	and use these immediately.
