On the fsx-id branch:
Replace the last invocations of the old svn_fs_x__dag_get_id.

* subversion/libsvn_fs_x/dag.c
  (make_entry): We only need the copy ID here and the full ID of the
                new node is readily available as well.
  (svn_fs_x__dag_clone_child): Use the new FS API ID getter.
  (svn_fs_x__dag_copy): Same. Reuse IDs that we already got.
