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.

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.
svn:r3327
make it clearer which warns are bugs,
make the control log event match its specification,
point out a bug in how we deal with failure when renewing the tls context.
svn:r3138
Stop treating the uint16_t's as null-terminated strings,
and stop looking at the byte after them to see if it's null,
because sometimes you're not allowed to look there.
svn:r3108
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.
svn:r3078
Stop keeping track of num_retries for apconns, since they expire
after 60 seconds anyway.
When warning about retrying or giving up, print the address, so
the user knows which one it's talking about.
svn:r3073
waiting for its connected cell, we were calculating time from when the
ap_conn was created. So if it waited say 20 seconds before being attached,
then we would immediately decide that the circuit had timed out.
Also, make circuit_dump_by_conn() display actual circuit progress,
including circuits that haven't been attached to the conn yet but
hope to when it finishes connecting.
svn:r3072
Put the check-if-requested-exitrouter-will-reject-us code in the
circuit_attach loop, so it gets checked periodically and not just
once at the beginning. This is useful in case the routerlist changes,
but also in case the address gets resolved into something that we learn
we'll reject.
svn:r3039
decide what exit node to use; based on a patch by geoff goodell.
needs more work: e.g. it goes bananas building new circuits when the
chosen exit node's exit policy rejects the connection.
svn:r3015
Now we can try setting an option but back out if it fails to parse, or
if it's disallowed (e.g. changing RunAsDaemon from 1 to 0).
Use parse_line_from_str rather than parse_line_from_file.
svn:r2692
sometimes circuit_get_open_circ_or_launch() can return 0 but not
return a circuit, e.g. because too many circuits have failed recently
so the new one didn't launch. we need to tolerate that.
svn:r2438
files have really old descriptors for the authdirservers, so we're
asking them in the new format because they're too old.
now we actually compare the version to a cutoff version, and act
appropriately.
also take this chance to use only >=0.0.8 servers for dns resolves,
because of the recent bugs. we'll bump to >=0.0.9pre1 once there are
some servers running that.
svn:r2380
bugfix: we were retrying the same circuit after getting a resolve
failure. so of course the next two tries would fail too. now we try
a new circuit each time (at most three times).
