openldap/servers/slapd/back-sql/entry-id.c
Pierangelo Masarati fbc11bd16a - added the capability to filter based on hasSubordinate attribute
to back-bdb, back-ldbm and back-sql (the latter with limitations);
- added handling of ":dn" attributes to extended rfc2254 filters
  and to matched value filter
- altered the behavior of get_mra() when a matching rule is given:
  now it checks whether it is compatible with the attribute syntax
  and, in case it is, the given mr is used.  In case of no type,
  the check is delayed when filtering
