On the log-addressing branch: Make svnadmin_tests.py 32 pass for format 7.
We get slightly different error codes and we must read the change list
location / offset from the l2p index file.

* subversion/tests/cmdline/svnadmin_tests.py
  (read_l2p,
   repo_format): new utility functions
  (set_changed_path_list): add support for format 7
  (verify_invalid_path_changes): update callers;
                                 expect changed output for format 7
