      Bug#54408: txn rollback after recovery: row0umod.c:673
      dict_table_get_format(index->table)
    
      The REDUNDANT and COMPACT formats store a local 768-byte prefix of
      each externally stored column. No row_ext cache is needed, but we
      initialized one nevertheless. When the BLOB pointer was zero, we would
      ignore the locally stored prefix as well. This triggered an assertion
      failure in row_undo_mod_upd_exist_sec().
    
      row_build(): Allow ext==NULL when a REDUNDANT or COMPACT table
      contains externally stored columns.
    
      row_undo_search_clust_to_pcur(), row_upd_store_row(): Invoke
      row_build() with ext==NULL on REDUNDANT and COMPACT tables.
