       Sets if the write must have been journaled before indicating success.

       Beginning  in  version  1.9.0, this function can now alter the write concern after it has been used in an
       operation. Previously, using the struct with an operation would mark it  as  "frozen"  and  calling  this
       function would log a warning instead instead of altering the write concern.

       • write_concern: A mongoc_write_concern_t.

       • journal: A boolean.

          void
          mongoc_write_concern_set_journal (mongoc_write_concern_t *write_concern,
                                            bool journal);
