OpenLDAP 2.1 -> Historic

OpenLDAP Software 2.1 is now considered Historic.  Users
of OpenLDAP Software 2.1 are encouraged to update to
at least latest "stable" release.  All Release
Engineering activities on the OPENLDAP_REL_ENG_2_1
branch are now official discontinued (they have been
informally discontinued for many months).
