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.

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.

c4411841d2 Avoid an integer underflow when the dir authority decides whether a
router is stable: we might wrongly label it stable, and compute a slightly
wrong median stability, when a descriptor is published later than now.

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wait til 0.1.1.x is obsolete.
