In the conflict resolver, start weeding out use of svn_ra_get_deleted_rev().

The ra_get_deleted_rev() function was good enough so far. But it will get
in the way once we start trying to find incoming moves in the log's changed
paths list.

* subversion/libsvn_client/conflicts.c
  (find_deleted_rev): Make the related repos_relpath/revision optional,
   so we can use this function in more contexts (e.g. forward update).
  (find_revision_for_suspected_deletion): Fix comment.
  (conflict_tree_get_details_incoming_delete): Replace use of
   svn_ra_get_deleted_rev() with our custom find_deleted_rev() log scan.
