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.

e572d5990c MSVC6 is apparently terrified of unnatural cross-breeding between uint64_t and double, and needs more persuasion than usual to cast one to the other. Issue identified by Frediano Ziglio; patch revised for minimal impact on non-MSVC6 compilers.

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wait til 0.1.1.x is obsolete.

0bfef523df simplify the tortls api: we only support being a "server", that
is, even tor clients do the same sort of handshake.

this has been true for years, so it's best to get rid of the

474c60b743 Cleanup on time-relaqted constants. New conventions:
1) Surround all constants by (parens), whether we'll be using them
     in a denominator or not.
  2) Express all time periods as products (24*60*60), not as multiplied-out
     constants (86400).
  3) Comments like "(60*60) /* one hour */" are as pointless as comments
     like "c = a + b; /* set c to the sum of a and b */".  Remove them.
  4) All time periods should be #defined constants, not given inline.
  5) All time periods should have doxygen comments.
  6) All time periods, unless specified, are in seconds.  It's not necessary
     to say so.

To summarize, the old (lack of) style would allow:

  #define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
  next_try = now + 3600;

The new style is:

  /** How often do we reattempt foo? */
  #define FOO_RETRY_INTERVAL (60*60)

  next_try = now + RETRY_INTERVAL;

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.

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.

cdc912714e I love the smell of C in the morning. Make router-download rules smarter (download more so long as we dont duplicate existing requests; relaunch at staggered intervals); relaunch one a minute or on failure; reset 60 minutes; always open 3 requests if we can; add authority opinion to networkstatus; make naming rule correct. There is a remaining bug where we retry servers too quickly; We need to look at that harder.

87f6d526fe Refactor new directory code a bit. Keep a big list of rolled-up router status info, including # of download failures (not yet used). Update this list from networkstatuses when they arrive, then update routers from this list. Only download 128 routers at a time, to avoid gargantuan URLs.
