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.

NEEDS REVIEW. Act on previous comment, and handle named servers differently: now, we allow multiple servers with the same name in the routerlist even if that name is reserved, but we check whether names are reserved when we try to look up routers by nickname. This is a minor security fix. This makes router_add_to_routerlist O(1). This is a backport candidate.

router_set_networkstatus() gets a list of status documents we asked for from
connection_dir_client_reached_eof(). However, as a cache we (sometimes?) just
ask for "all". router_set_networkstatus() would freak out over that, meaning
it would log a warning and drop the status document instead of caching it
as it is supposed to. Now we let router_set_networkstatus() know if the
data comes from an all-request so it can do the right thing.
