+  o Minor bugfixes (address selection):
+    - When the fascist_firewall_choose_address_ functions don't find a
+      reachable address, set the returned address to the null address and port.
+      This is a precautionary measure, because some callers do not check the
+      return value.
+      Fixes bug 24736; bugfix on 0.2.8.2-alpha.
