On the log-addressing branch:  Support arbitrary compatibility
versions when selecting the repository format.  

* subversion/tests/svn_test_fs.c
  (make_fs_config): set the generic compatibility version option
                    that should work for all selected versions
                    but keep the old options as well for better
                    test coverage
