Release 4.7: Replication API

The Berkeley DB base replication API DB_ENV->rep_elect(), DB_ENV->rep_get_nsites() DB_ENV->rep_set_nsites(), DB_ENV->rep_get_priority() and DB_ENV->rep_set_priority() methods now take arguments of type u_int32_t rather than int. Applications may need to change the types of arguments to these methods, or cast arguments to these methods to avoid compiler warnings.
