Change - bdb_tool_entry_put always "sorts" entries:

Browse source 
instead of just calling bdb_next_id, it calls bdb_dn2id to see if the
    current entry already has an ID. If so, it uses it.
  if not, it recurses to see if its parent exists, and does dn2id_add from
    the database suffix back to the current entry.
