SASL mech removed from backend bind callback (as SASL is managed by frontend)
Changes to some backends are untested (as I don't have all dependent
  software install)

and other error handling changes

Don't use LDAP_OPERATIONS_ERROR for internal errors.  Use LDAP_OTHER
instead.  (more changes needed in this area)

non-bind requests while a multi-step SASL bind process
is under to connection.c.  Return LDAP_OPERATIONS_ERROR,
not LDAP_SASL_BIND_IN_PROGRESS.

Only return SLAPD_DISCONNECT with a send_ldap_disconnect()
was called.
Add initial code for support predetermined filter results
when filter is undefined (or known to be true or false).

Noticed that abandon and unbind don't have control support... something for
another day.

user password.  Likely to be modified to use bind control
instead.  Use of modify deprecated in favor mechanisms that
support passwords stored externally to the directory (such
as in a SASL service).
Modified slapd extended operation infrastructure to support
backend provided extended operations.

See README 1.27 log.

s/dn_normalize/dn_validate/
s/dn_normalize_case/dn_normalize/

and back-ldbm are preserved, they only use the up-cased DNs. back-passwd
uses the mixed-case DN. All others are using mixed-case DN, may need more
fixing.

Replace old Id as needed (back-tcl).
Leave updating of contribWare to contributors (for now).

Fix Statlog() formats, remove an implicit int, include <ctype.h> for isspace().

updated patch submitted Philipp Klaus <ldapml@internet.access.ch>
Can be enabled using --enable-multimaster.  TODO:
Replication test likely should be adjusted to test multimaster environment.

	add MODRDN newSuperior support
	add '#' support to ldapmodify (but not slurpd and ldbm tools)

an OID or a proper type string (letter followed by 0 or more

NULL does not meet basic syntax rules.

didn't bother to acquire)...

Includes support for update referral for each replicated backend.
	Reworked replication test to use update referral.
Includes major rewrite of response encoding codes (result.c).
Includes reworked alias support and eliminates old suffix alias codes
(can be emulated using named alias).
Includes (untested) support for the Manage DSA IT control.
Works in LDAPv2 world.  Still testing in LDAPv3 world.
Added default referral (test009) test.

Modify ldap_result to assert returned error is not an one reserved
for API use.
Modify frontend LDAP operation routines to return an error code.
The returned value will be used to determine if an unsolicited notification
should be sent to the client.
Need to review returned error codes.  Namely some LDAP_PROTOCOL_ERROR
will like need to be changed (as they will cause unsolicited notifications).

Add place holder for handling LDAPv3 extended operations (coming soon).

added lber_types.h.nt, lber_types.h.in
removal of NULLxxx internal macros (in favor of NULL).
ch_free added to slapd,slurpd/ch_malloc.c
#define free ch_free (should be removed after s/free/ch_free/g) in proto-slap.h
ch_malloc and friends use ber_memalloc and friends
