Fix Description:
. Fix for llistRemoveCurrentAndGetNext (llist.c) in commit
  f92f3a6e91498770aa8e93b6842ba752d4ed279a was not correct.
. Undo the changes made in ldbm_back_add, ldbm_back_modrdn
  (ldbm_add.c, ldbm_modrdn.c) in commit
  f92f3a6e91498770aa8e93b6842ba752d4ed279a.
. urp.c: In the original design, if op_result is LDA_SUCCESS and
  the return code is -1, the operation is skipped, but the max
  csn is updated in RUV.  Currently, we have no way to do so.
  This patch eliminates the cases: 2 in urp_add_operation and 1
  in urp_modrdn_operation are now LDAP_UNWILLING_TO_PERFORM; 1 in
  urp_modrdn_operation (the existing entry is the same as the
  target one) returns 0.
