84c81e0783 Annotate circuits w/ whether they aim to contain high uptime nodes and/or 
high capacity nodes. When building circuits, choose appropriate nodes.

New config option LongLivedPorts to indicate application streams
that will want high uptime circuits.

When attaching a stream to a circuit, pay attention to its requirements.

This means that every single node in an intro rend circuit, not just
the last one, will have a minimum uptime.

Boost the min uptime from an hour to 24 hours.

45eb8d9660 if you're a server and the auth dirservers are down, go to any other 
server. only give up hope on network reachability when no other servers
are reachable either.

f468ff04ea when we haven't fetched a directory yet, or the last time we 
tried they were all unreachable, assume we are not connected to
the network.

when an application request comes in during this state, be
optimistic and assume we just reconnected. fetch a new directory
and if it works, begin making circuits.

now by default they refuse router descriptors that have non-IP
or private-IP addresses.

fe6eb34a10 Solaris CC freaks out if isspace and friends get anything other than an int. We learned that, so we casted. But it is also a bad idea to cast a signed char to an int and expect things to work on win32. Now we cast to unsigned char, then to int, then pass to isspace. Ug

ef6c9d18e7 New circuit building strategy: keep a list of ports that we've used in the past 6 hours, and always try to have 2 circuits open or on the way 
that will handle each such port. (We can extend this to include addresses
if exit policies shift to require that.) Seed us with port 80 so web
browsers won't complain that Tor is "slow to start up".

This was necessary because our old circuit building strategy just involved
counting circuits, and as time went by we would build up a big pile of
circuits that had peculiar exit policies (e.g. only exit to 9001-9100)
which would take up space in the circuit pile but never get used.

Fix router_compare_addr_to_addr_policy: it was not treating a port of *
as always matching, so we were picking reject *:* nodes as exit nodes too.

If you haven't used a clean circuit in an hour, throw it away, just to
be on the safe side.

This means after 6 hours a totally unused Tor client will have no
circuits open.

11d330be5e Tweaks to prevent obsolete restarting tors from hammering the dirservers. (1) Cache a received directory as soon as the signature checks out. (2) Treat a cached directory as "recent" based on its mtime. (3) If we have a recent directory, we dont need to fetch a newer one for DirFetchPostPeriod. This needs review!
