Make 'svn resolve' notify about moves which are broken.

Notifications currently only show the move source path,
and look like this:

  Breaking move with source path 'A/B/f'.

We'd need to extend svn_wc_notify_t to show the destination path as well.

Also, 'svn revert' does not yet provide these notifications. I'm not sure
yet whether 'svn revert' should provide them. It would be an extra chunk
of work anyway which can be done in a later commit if necessary.

* subversion/include/svn_wc.h
  (svn_wc_notify_action_t): Add svn_wc_notify_move_broken.

* subversion/libsvn_wc/conflicts.c
  (resolve_tree_conflict_on_node): Pass notification function/baton to
   svn_wc__db_resolve_break_moved_away() (and to the _children() variant).

* subversion/libsvn_wc/wc_db.h
  (svn_wc__db_resolve_break_moved_away,
   svn_wc__db_resolve_break_moved_away_children): Add notify func/baton params.

* subversion/libsvn_wc/wc_db_update_move.c
  (break_moved_away_children_internal, 
   svn_wc__db_resolve_break_moved_away,
   svn_wc__db_resolve_break_moved_away_children): Notify broken moves.

* subversion/svn/notify.c
  (notify): Handle svn_wc_notify_move_broken. Add a missing 'break' while here.

* subversion/tests/cmdline/svntest/actions.py
  (_run_and_verify_resolve): Accept the new notifcation, but don't require it.
   This avoids breaking existing tests that resolve conflicted nodes which
   have been moved.
