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.

388ac4126a If we are using an exit enclave and we can't connect, e.g. because 
its webserver is misconfigured to not listen on localhost, then back
off and try connecting from somewhere else before we fail.

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.

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wait til 0.1.1.x is obsolete.

c660a0f6a2 More DNS fixes. Send meaningful TTLs back to the client when 
possible.  Cache at the server side independently from the TTL, to
prevent attackers from probing the server to see who has been asking

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.

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;
