Bug in parsing Address line in torrc

[Ian Goldberg <iang@xxxxxxxxxxxxxxx>]

Nick et al.,

Mashael and I uncovered a little bug in the torrc parsing code in
src/or/config.c.  If Address is set to a dotted quad, tor_inet_aton
returns 1, and stores the address in in.s_addr, but that field is then
never copied out to the addr variable.  Here's a patch.

+    addr = ntohl(in.s_addr);
   }
 
   addr_string = tor_dup_ip(addr);


This is against 0.2.3.0-alpha-dev.

Thanks,
