Back in 5e762e6a5c, non-exit servers
stopped launching DNS requests for users. So there's no need for them
to see if their DNS answers are hijacked.
Patch from Matt Pagan. I think this is a 965 fix.
For a client using a SocksPort connection and IPv6, the connect reply
from tor daemon did not handle AF_INET6 thus sending back the wrong
payload to the client.

When we have more than two return values, we should really be using
an enum rather than "-2 means this, -1 means that, 0 means this, and
1 or more means a number."
It's increasingly apparent that we want to make sure we initialize our
PRNG nice and early, or else OpenSSL will do it for us. (OpenSSL
doesn't do _too_ bad a job, but it's nice to do it ourselves.)
We'll also need this for making sure we initialize the siphash key
before we do any hashes.
I've made an exception for cases where I'm sure that users can't
influence the inputs. This is likely to cause a slowdown somewhere,
but it's safer to siphash everything and *then* look for cases to
optimize.
This patch doesn't actually get us any _benefit_ from siphash yet,
since we don't really randomize the key at any point.
(There is no longer meaningfully any such thing as a HS authority,
since we stopped uploading or downloading v0 hs descriptors in
0.2.2.1-alpha.)
Implements #10881, and part of #10841.
This patch removes an "if (chan)" that occurred at a place where
chan was definitely non-NULL. Having it there made some static
analysis tools conclude that we were up to shenanigans.
This resolves#9979.
Right now this accounts for about 1% of circuits over all, but if you
pick a guard that's running 0.2.3, it will be about 6% of the circuits
running through that guard.
Making sure that every circuit has at least one ntor link means that
we're getting plausibly good forward secrecy on every circuit.
This implements ticket 9777,
It's possible to set your ExitNodes to contains only exits that don't
have the Exit flag. If you do that, we'll decide that 0 of your exits
are working. Instead, in that case we should look at nodes which have
(or which might have) exit policies that don't reject everything.
Fix for bug 10543; bugfix on 0.2.4.10-alpha.
According to control spec, longname should not contain any spaces and is
consists only of identy_digest + nickname
added two functions:
* node_get_verbose_nickname_by_id()
* node_describe_longname_by_id()
