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.

c644886c38 bugfix: When we were checking to see if an ap_conn should time out
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.

954570486f Resolve a FIXME: use identity comparison, not nickname comparison, to
choose circuit ID types.  This is important because our view of "the
nickname of the router on the other side of this connection" is
skewed, and depends on whether we think the other rotuer is
verified--and there's no way to know whether another router thinks you
are verified.

For backward compatibility, we notice when the other router chooses
the same circuit ID type as us (because it's running an old version),
and switch our type to be polite.
