commit 44237aca4c6173637e7e70d6e971fd0dce799c07
Author: Damian Johnson <atagar at torproject.org>

Drop everything related to connection hostnames
This has been dead code for years. Once upon a time arm resolved which is neat!
But this involved active queries, which leaks a relay's circuits to their dns
resolver.
We can fix this by querying all relays (rather than just ours), but likely
overly wasteful. Needs more investigation. Regardless, it's been dead code for
quite some time now so about time we drop it. We can re-introduce something
when we have hostname resolution once again.
