  (setup_and_sync): Modified to accept two bools is_src_ra_local and 
                    is_dest_ra_local. If True, the init, sync and 
                    copy_revprops will use the ra_local URLs.

  (run_test):       Percolate is_src_ra_local and is_dest_ra_local.
                    Fix call of setup_and_sync.

  (fd_leak_sync_from_serf_to_local): New test for Issue 3870.
