cleanups in the working copy update editor.

* subversion/libsvn_wc/update_editor.c
  (check_wc_root): Shuffle and rename some arguments.
  (already_in_a_tree_conflict): Add an iterpool.
  (close_directory, close_file): Use our library-internal propget function.
  (svn_wc_get_update_editor3, svn_wc_get_switch_editor3): Add a comment
    about rev'ing the API in the future.
  (check_wc_root): Remove the early out for going beyond the wcroot, since
    we have an abspath.  Also, use the local_abspath throughout.
  (svn_wc_is_wc_root, svn_wc__strictly_is_wc_root, svn_wc_get_actual_target):
    Use an abspath to call check_wc_root().
