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 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.
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.
