	* default.exp: Add rudimentary support for multiple passes.  For
	now, iterate over a few combinations of des_krbtgt and assorted
	enctype lists.  Will eventually allow for separate krb5.conf files
	for clients and servers.  Add varibles RLOGIN and RLOGIN_FLAGS to
	permit run-time configuration of rlogin program if necessary.  Set
	up an onexit handler that calls stop_kerberos_daemons.  Replace
	many uses of doubled-up send_log and verbose with single calls to
	verbose -log.  Replace instances of send_error with perror where
	appropriate, since this will cause successor test to fail, which
	is usually what we want.
	(setup_root_shell): Replace calls to untested with calls to
	unsupported; also use note for explanatory text previously printed
	using untested.  Add match string for "connection refused" and
	collapse common code into a single expect clause by using the -re
	flag.
	(start_kerberos_daemons): Conditionalize calls to fail based on
	$standalone; in the !$standalone case, call perror instead.  Calls
	to fail and pass for a given test should have consistent strings,
	and extraneous calls to fail should not be made in order to keep
	the total number of passed and failed tests constant regardless of
	success of setup steps.  Much remains to be done in this area
	though.
