build md5-utils

2000-10-27    <jpr@helixcode.com>

	* Makefile.am: build md5-utils

	* md5-utils.c: Make part of util, get rid of camel stream util
	function include string.h

	* md5-utils.h: ditto

2000-10-27    <jpr@helixcode.com>

	* providers/pop3/Makefile.am: Tidy up build

	* providers/smtp/Makefile.am: ditto

	* Makefile.am:  Move md5-utils.[hc] to e-util because the
	addressbook is going to use md5 hashes for pilot syncing.
	Maybe the calendar conduits as well because this is a good idea
	Chris had.
