[PATCH] #3493 svn patch skips missing directories

Hi!

[[[
Fix #3493 - svn patch skips missing dirs.

* subversion/libsvn_client/patch.c
  (svn_client_patch): Replace the last adm_access calls. Needed to be
    able to use the write-locks in svn_client__make_local_parents().
  (apply_textdiffs, apply_one_patch): Change ctx parameter to be non
    const.
  (apply_one_patch): Create intermediate missing dirs.
  (resolve_target_path): Don't mark the target to be skipped if there is
    no containing dir. Walk the tree to the wc-root checking if one of
    the dirs above our target is scheduled for deletion.

* subversion/tests/cmdline/patch_tests.py
  (patch_add_new_dir): New. Tests for adding files with missing dirs and
    the case where one of the dirs above is scheduled for deletion.

Right now the code does not skip when one of the dirs in the patch
file is a wc file. But I'm not sure that it's needed.
