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.

part fails if it does.

Modified by me to dn_*() and attr_*() functions and to use
uidObject and to handle search scopes better.  Could use some
more work.  A fun project for anyone wanting to learn how
backends work.
Modified dn_parent and dn_rdn to accept be=NULL (to bypass
be_issuffix check).  These functions should be generalized
and moved to -lldap.  A project for another day.

Remove disable write sync (dbcachenowsync) in master (for concurrency test).

Building tests/progs/*.c in the main build process.
==> Test-suite must be called by 'make test', or 'make test-bdb2'

  correctness of locking schemas in backends.
In back-bdb2 open NEXTID during startup and close at shutdown.

Integration into ./configure ( --enable-bdb2 ).
Adaptation of the test-suite ( 'make' -> ldbm; 'make bdb2-local' -> bdb2 ).
Minor fixes in slapd/libldbm.

initialization after reading slapd.conf, and before starting the daemon

introduction of pid/agrs parameters to the test-suite slapd.conf files;
creation of sub-directory test/var for storage of pid/args files during test;
update of the slapd and slapd.conf man pages.
(The change reduces dependency on ldapconfig.h, since SLAPD_PIDEXT
 and SLAPD_ARGSEXT are deleted from the code.)

Update slap_op to maintain dn and ndn (derived from conn->c_dn).
Update ldbm_back_bind to return actual bound dn (including rootdn)
	for use in slapd_conn.  Other backends use client dn.
Modify other codes to use ndn (normalized uppercase dn) most everywhere.
Aliasing, Suffixing and modrdn could use more work.
Applied suffixing to compare and modrdn.

add/merge as we now free strings agressively.  Improved debug
message to include name of missing required attribute and added
check for 'operational attributes'.  This check should be used
everywhere we need to test for operational attributes (add/modify).
Also, enabled schema checking for tests (and fixed resulting
problems by adjusting oc.conf).

  "Check that the entry has no writers before removing it from the
  cache" sounds more sensible to me than "check that it *has* writers"
  before removing it.
I've also changed the default cachesize for tests to 4.  This
should help discover such problems.

	adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however
	we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!
