a1f1fa6ab2 Checkpoint in-progress fixes: 
Add 'testing' circuit purpose, for reachability testing.
Notice when our IP changes, and reset stats.
Try to pull down a directory via Tor to see if our DirPort is working.
Try to extend a circuit back to us to see if our ORPort is working.
Only publish a descriptor if they're both reachable.

These mostly work, and I'd better get them in before I cause conflicts.

bbaa3c7792 Implement more control spec functionality 
- Mapaddress
- Postdescriptor
- GetInfo on descriptors

Required changes elsewhere:
- Keep the most recent running_routers_t in the routerlist_t. That way we
  can learn about new routers and remember whether we were last told that
  they were up or down.  Also enables more simplifications.
- Keep the signed descriptor inside routerinfo_t.  This makes
  descriptor_entry_t in dirservers.c unneeded.
- Rename AddressMap (the verb) to MapAddress. Keep AddressMap as a noun.
- Check addresses for plausibility before mapping them.

d273891107 if we fetch the dir from a mirror that has a wildly skewed 
clock, then don't bother checking recommended-versions: it will
just make us sad.

as a side effect, people running obsolete versions and whose
clocks are wildly skewed will not be auto-shut-down. but they
will still get warns about their clock skew.

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.

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.

52676364b9 bugfix: router_exit_policy_rejects_all() was broken, so we were 
sometimes picking middleman nodes as our last hop, which wasn't
very useful.
