 * any other's), end the batch to wait for replies for all outstanding
 * queries.  The output parameters of each query are initialized to NULL
 * or -1 as appropriate.

 * LDAP searches are sent one by one without waiting (i.e., blocking)
 * for replies.  Replies are handled as soon as they are available.
 * Missing replies are waited for only when idmap_lookup_batch_end() is
 * called.
 *
 * If an add1 function returns != 0 then abort the batch by calling
 * idmap_lookup_batch_end(), but note that some queries may have been
 * answered, so check the result code of each query.
