Comment (by teor):

 Ugh, I disliked the way I added `int is_ignored:1` to addr_policy_t. It
 was an ugly design.

 Instead, I added `int *malformed_list` to the arguments of
 router_parse_addr_policy_item_from_string. It is set to 1 if the entire
 list should be ignored, and 0 if just the current item should be ignored.

 I also found a lurking NULL-dereference bug in my additions to
 router_parse_addr_policy_item_from_string and fixed it.

 See my branch `bug16069-exit-policy-inconsistent-v4`.
