2249180b60 bugfix: if you find yourself reachable, then don't ever make any client 
requests (so you stop predicting circuits), then hup, then later your
IP changes, you won't think circuits are working so you won't try to
test reachability, so you won't publish.

892f671f59 Define a schedule for how long to wait between retrying 
application connections. Rather than waiting a fixed amount of
time between each retry, we wait only 5 seconds for the first,
10 seconds for the second, and 15 seconds for each retry after
that. Hopefully this will improve the expected experience.

Addresses bug 297.

e1f30a5f21 when we find our dirport to be reachable, mark our descriptor 
dirty so we'll tell the world. (fixes bug 306 reported by pnx)

ac258d2cc8 Start publishing one minute or so after we find our ORPort 
to be reachable. This will help reduce the number of descriptors
we have for ourselves floating around, since it's quite likely
other things (e.g. DirPort) will change during that minute too.

9db7b2c068 Allow servers with no hostname or IP address to learn their IP address 
by asking the directory authorities. This code only kicks in when you
would normally have exited with a "no address" error.

This design is flawed, though, since the X-Your-Address-Is header is not
authenticated, and doing it this way introduces too many new attacks. The
right answer is to give IP address hints inside the HELLO cell; much of
this code can be reused when we switch.

c4411841d2 Avoid an integer underflow when the dir authority decides whether a 
router is stable: we might wrongly label it stable, and compute a slightly
wrong median stability, when a descriptor is published later than now.

05d0b70573 Get rid of the router_retry_connections notion. Now routers no longer 
try to rebuild long-term connections to directory authorities, and
directory authorities no longer try to rebuild long-term connections to
all servers.

We still don't hang up connections in these two cases though -- we need
to look at it more carefully to avoid flapping, and we likely need to
wait til 0.1.1.x is obsolete.
