- Introduce cap_check_td() to reflect suser_td()
    - Introduce non-portable cap_from_text2_np(), which converts a
      text-form capability to an internal form relative to an existing
      capability, and non-portable cap_to_text2_np(), which accepts
      a flag argument specifying more about the text output format.
    - Introduce CTT_* flags controlling the behavior of
      cap_to_text2_np().
