7aae63994f Recover better from TCP connections to Tor servers that are broken but
don't tell you (it happens!); and rotate TLS connections once a week.

1) If an OR conn becomes more than a week old, make it obsolete.
2) If it's obsolete and empty, kill it.
3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
5) When we time out on circuit building on the first hop, make that
   connection obsolete.

logs in cases where a calling function's log was downgraded and we wouldn't
get any log message otherwise.

61ea516885 Check for named servers when looking them up by nickname;
warn when we'recalling a non-named server by its nickname;
don't warn twice about the same name.

Fix a bug in routers_update_status_from_networkstatus that made nearly
all clients never update routerinfo_t.is_named.

Try to list MyFamily elements by key, not by nickname.

Only warn about names that we generated ourself, or got from the local
user.

On TLS handshake, only check the other router's nickname against its
expected nickname if is_named is set.

a120cc20c1 Dirservers now do their own external reachability testing of each
Tor server, and only list them as running if they've been found to
be reachable.

Dirservers also log trouble servers, but only start complaining loudly
after they've been up for an hour, to reduce false positives. We still
need to do something about the fact that it is quite loud when there
are many trouble servers.

f35ef825f9 Our logic to decide if the OR we connected to was the right guy
was brittle and maybe open to a mitm for unverified routers.

Now we be sure to check the digest, and if the nickname he claims is
not a verified one then we don't care what nickname he claims.

aff308e6d9 reenable the part of the code that tries to flush as soon as an OR outbuf
has a full tls record available. perhaps this will make OR outbufs not grow
as huge except in rare cases, thus saving lots of cpu time plus memory.

324b192f68 Make Tor use Niels Provos's libevent instead of it's current
poll-but-sometimes-select mess.  This will let us use faster async cores
(like epoll, kpoll, and /dev/poll), and hopefully work better on Windows
too.

There are some fairly nasty changes to main.c here; this will almost
certainly break something.  But hey, that's what alphas are for.

70075933c6 stop checking for clock skew, even for servers.
this means we are vulnerable to an attack where somebody recovers
and uses a really old certificate. however, if they do that, they
probably can get our identity key just as easily.
