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wait til 0.1.1.x is obsolete.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
stale code.

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;

92ef9e37e7 Add a new config option ExitPolicyRejectPrivate which defaults to 1.
This means all exit policies will begin with rejecting private addresses,
unless the server operator explicitly turns it off.

Also, make our code to remove redundancies in the exit policy smarter,
so it can detect "reject foo, reject bar, reject *" patterns.

Lastly, we can get rid of the "exit policy implicitly accepts" code,
since we make everything more explicit now.

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   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask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

  download redundancy checking work.

directory.c, or.h, router.c, routerlist.c:
- Start on logic to note when networkstatus downloads fail.

dirserv.c, routerlist.c, routerparse.c:
- Start maintaining an is_named field in routerstatus_t.  Don't
  actually look at it yet.

dirserv.c, routerlist.c:
- Remove expired networkstatus objects.

or.h:
- Make some booleans into bitfields
- Add prototypes

routerlist.c:
- Sort networkstatus list by publication time
- 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.

54a6a8f0ef Start implementing the server side of the new directory protocol.
Probably very buggy, since I can't actually run an authdir.

Features
- Generate and publish new network-status format
- Code to cache and re-serve network-status objects generated by others.
- Publish individual descriptors (by fingerprint, by "all", and by
  "tell me yours.")  [Still needs compression logic]
- Publish client and server recommended versions seprately.
- Add digest of descriptor to routerinfo_t, so we can track them better, and
  length, so we can server them more easily.

Cleanups
- Unify code to sign directory-like things
- Make resolve_my_address() able to tell you which name it wound up resolving.
- Unify code to store and serve directory-like things so it all uses
  cached_dir_t.
- Unify code to set the value of cached_dir_t objects.
