including:
- fixes according to new API changes
- closing db connection in connection_destroy callback, not unbind
- support of new schema code, samples changed accordingly

Remove slurpd kbind support as this requires LDAPv2
Backout back-ldbm/referrals.c update_ndn hack

	Slurpd incorrectly sends a separate attribute for each value of an
	attribute which caused slapd to complain.  Hacked slapd/add.c
	to merge values.
	Slurpd uses version 2 and hence cannot set ManageDSAit.  Hack
	slapd/back-ldbm/referral.c such that if update_ndn matches
	o_ndn, no referrals are returned.
Fix replication tests
	ldapmodify must be made against master as no rebind proc exists
	final ldapsearch should not chase
Fix referral tests
	Use -C option as needed

-R now ignored
-C added to chase.  No rebind proc yet, no checking of appropriate authentication.

-L now limits output to LDIFv1 for compatibility reasons.  No

an internal flag set.  Used for SEQUENCE testing.  Flag must
be set using debugger.  Modified ber_printf to use new format
were needed for extensibility testing.

Added first cut -lldap support for extended responses.
Modified ldapsearch(1) to handle v3 search references when not
chasing.  Also added extended/unsolicited notification handling
and extended partial response handling.  Changes include a
number of LDIF enhancements.

Fixed getpassphrase() returns NULL bugs
