47d3e23155 note another bug: we complain that a router doesn't exist,
because it's down so we never fetched it so it doesn't exist.

no reason not to proceed if all the other checks are ok -- we just

building.

Make the warnings about invalid and unnamed nodes scale better, and
update the text of the warnings.

Change router_have_minimum_dir_info() to only be happy when it has
enough network-statuses ("more than half") to be willing to actually
build circuits.

Not yet done: when we fail to get a networkstatus that we wanted, and
!router_have_minimum_dir_info(), we should retry it quicker than a whole

581795f41d auth dir servers were only modifying a server's is_running field

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;

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.
