It's now committed and debugged:

* svn_delta_path_driver_start
* svn_delta_path_driver_step -- drives the editor to a new path
* svn_delta_path_driver_finish

And the all-at-once path driver is slightly upgraded: the new version svn_delta_path_driver3() passes the 'editor' and 'edit_baton' to the callback, which makes most implementations a bit simpler.

Only used in "unshelve", so far, and I might soon replace that with something else for Shelving v3, but I'm sure it will be useful anyway.
