From 5109de562604c334fee2a0778ff15ad93a4b1191 Mon Sep 17 00:00:00 2001
From: Nick Mathewson <nickm@torproject.org>
Date: Fri, 12 Nov 2004 19:39:13 +0000
Subject: Rename exit_policy to addr_policy, since it gets used for SOCKS and
 directory connections too.  Make all policies get validated in
 options_validate, and make SOCKS/directory policies get set in options_act.
