Keith Buck 5bd79c2c56 res.c: Try other servers if errors or corrupt replies are encountered.
Currently, the resolver treats SERVFAIL, NOTIMP, and REFUSED queries the
same as NXDOMAIN, but this really should not be the case. Instead, if
the DNS server errors on our request or provides an invalid request, try
another server.

Also, count DNS server errors in addition to timeouts and avoid these
undesirable servers.

Jilles Tjoelker db3efb7ac2 Allow the resolver to process longer hostnames,
for the benefit of some DNSBLs like the "TorDNSEL service".
