Minor fix: add code to eventdns so it can free memory on shutdown. This should help valgrind and dmalloc freak out less.

Marge changes from libevent evdns to our eventdns. Most are cosmetic, but one or two are stability-related. This should make it easier to push our changes back towards libevent.

Backport candidate: Fix a long-standing server-side DNS bug. When a
...
client asks us to resolve (not connect to) an address, and we have a
cached answer, give them the cached answer. Previously, we would give
them no answer at all.

Instead of just checking known-invalid addresses for DNS hijacking, we
now check randomly generated addresses, and if too many of them map to
the same IP, we assume that IP is the destination of a DNS hijack
attempt.
A little bird tells me that some DNS hijackers think that declining to
give an A record for RFC2606 addresses (like .invalid and .example)
makes them more standards compliant. Standardswise, this is like an
illicit brothel making sure that nobody has pulled the tags off the
mattresss, but that doesn't get us out of working around it.
