Refactor connection_t into edge, or, dir, control, and base subtypes.  This might save some RAM on busy exit servers, but really matters most in terms of correctness.

581795f41d auth dir servers were only modifying a server's is_running field
when they created a network status. so if nobody asked for a
network status, they would never discover that any servers are
is_running, so they could never build a circuit.

652e1899ac "How about 'never'? Does 'never' work for you?"
Weasel says circuit_get_by_conn is his main timesink.  Most of its
users were just checking whether OR conns had circuits, so add a
circuit count to OR conns, and check that. One was
circuit_about_to_close_conn, which was doing an O(n^2) series of calls
to get all circs on an OR conn, so make an O(n) function for that.
Finally, circuit_get_by_edge_conn was using it as a sanity test that
has been around for a while but never found any actualy insanity, so
kill that.

circuit_get_by_conn is finally dead, which is good, since it was never
sane to begin with.

7aae63994f Recover better from TCP connections to Tor servers that are broken but
don't tell you (it happens!); and rotate TLS connections once a week.

1) If an OR conn becomes more than a week old, make it obsolete.
2) If it's obsolete and empty, kill it.
3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
5) When we time out on circuit building on the first hop, make that
   connection obsolete.

- Function to remove old (older than 10 days) networkstatus objects.
- Function to set a list of routerinfo_ts' status info from the
  current set of networkstatus objects.
- Function to tell which routerinfos we need to download based no the
  current set of networkstatus objects.
- Do not launch a networkstatus download if a redundant one is in progress.
