Try to compile with fewer warnings on irix64's MIPSpro compiler /
 environment, which apparently believes that:
   - off_t can be bigger than size_t.
   - only mean kids assign things they do not subsequently inspect.
 
 I don't try to fix the "error" that makes it say:
 
 cc-3970 cc: WARNING File = main.c, Line = 1277
   conversion from pointer to same-sized integral type (potential portability
           problem)
 
     uintptr_t sig = (uintptr_t)arg;
 
 Because really, what can you do about a compiler that claims to be c99
 but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
 is safe?

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wait til 0.1.1.x is obsolete.

20e66a799b Resolve problem found by weasel: the v1 directory was including 
servers as much as 48 hours old, because that's how the new
routerlist->routers works. Now only include them if they're
20 hours old or less.

if it doesn't have an approved-routers file. if it does,
read it and parse it as usual.

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;

b67a5ba498 lower the reachability timeout, so we're more likely to act 
quickly if a server stops being reachable.

1fc5eb329b We screwed up in anticipating how to add new dirservers: 
Old servers won't realize they're supposed to stay connected
to the new dirservers, so they'll expire connections to them,
but that means the dirservers will list them as unreachable.

So the fix is to stop requiring an open connection when deciding
if a server is reachable. This makes us slightly less accurate,
but at least it will work.
