be implemented.

The rest of this change mostly contains random ideas taken from
mod_ssl.  The purpose is to get the repository in sync with the
code I am testing.  I still can't manage to make Netscape send
its certificate to slapd, though it works with Apache/mod_ssl
(with the same certificates).  Trying s_client against both
does not shed any light.  If anyone manages to make it work,
please let us know.

arena corruption.

ldap_modify: delete of last attribute value should delete attribute (ITS#229)
thr_nt: use sleep to yield

Set flags without relying on errno (this change may be gratuitous
or wrong).

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.

More error checking and reporting.
Slowly getting there, SSL_accept succeeds now, but connection breaks
immediately after that (my glue logic with slapd is broken).

Change temporarily the default protocol from TLSv1 to SSLv3 with
fallback to SSLv2.  This seems necessary for slapd to accept connections
from Netscape.
Try to set the cipher list in the default context.  Does not semm to
work yet.

Add use of TLS_LIBS so that test tools compile

Add tls.c
Add use of TLS_LIBS so that test tools compile

First version of TLS glue for SSLeay/OpenSSL originally written by
Bart Hartgers.  Untested.

Add digest md5 codes to -lldap/-lldap_r (work in progress)
