 As part of the fix to #2279 we committed 411ec3c0 which made tor refuse
 socks connections to private/local addresses if .exit isn't specified.

 I just got this line in my tor log:
 Mar 31 14:45:52.116 [Warning] Rejecting SOCKS request for anonymous
 connection to private address [scrubbed]

 I believe it happened because some exit relay answered my pidgin's request
 for the aim server with 192.168.1.1 or the like, and then my Tor cached
 that address even though it would map requests to it in the future and
 then refuse them.

 I guess that means we should either revert that part of 2279 or add a
 check when we're adding an addressmap.
