TOR resolver appends localdomain to DNS requests

[peterpramb]

For some time now I see lots of AAAA requests in the query log of my domain's authoritative nameserver
looping back from my upstream resolvers. Here are some examples:

query: piichandiary.blog71.fc2.com.<mydomain> IN AAAA -E
query: fwing.blog6.fc2.com.<mydomain> IN AAAA -E
query: nekosen.blog61.fc2.com.<mydomain> IN AAAA -E
query: tsuboriba.blog71.fc2.com.<mydomain> IN AAAA -E
query: 405405.blog65.fc2.com.<mydomain> IN AAAA -E
query: ocucoop2006-mon-e.seesaa.net.<mydomain> IN AAAA -E

Since the host running TOR is IPv6 enabled the resolver first tries to lookup IPv6 addresses. However
the problem is not the AAAA query, which should be "resolved" by #280, but the fact that the host's
domain name is added if the first query failed.

This even works with non-FQDN names, eg. use this to access my webserver:

​http://www.peterp1701.exit/

As a workaround someone can set LOCALDOMAIN=. in the TOR init script, but appending the default domain
and using the domain search list should really be disabled by TOR itself.

This should be fixed in 0.1.2.x-final, assuming that we move everything over to the new eventdns.c
internal resolver. But just to be sure, I'm making the dnsworker code work too.

Fixed in svn repository as of r8225; should be fixed in next alpha release.
