ldb: version 1.2.2

* Bug #13017: Add ldb_ldif_message_redacted_string() to allow debug
              of redacted log messages, avoiding showing secret values

* Bug #13015: Allow re-index of newer databases with binary GUID TDB keys
              (this officially removes support for re-index of the original
              pack format 0, rather than simply segfaulting).
* Avoid memory allocation and so make modify of records in ldb_tdb faster
