poll-but-sometimes-select mess. This will let us use faster async cores
(like epoll, kpoll, and /dev/poll), and hopefully work better on Windows
too.
There are some fairly nasty changes to main.c here; this will almost
certainly break something. But hey, that's what alphas are for.

tried they were all unreachable, assume we are not connected to
the network.
when an application request comes in during this state, be
optimistic and assume we just reconnected. fetch a new directory
and if it works, begin making circuits.

make it clearer which warns are bugs,
make the control log event match its specification,
point out a bug in how we deal with failure when renewing the tls context.

Put the check-if-requested-exitrouter-will-reject-us code in the
circuit_attach loop, so it gets checked periodically and not just
once at the beginning. This is useful in case the routerlist changes,
but also in case the address gets resolved into something that we learn
we'll reject.

- DirFetchPeriod for fetching full directory,
- StatusFetchPeriod for fetching running-routers,
- DirPostPeriod for posting server descriptor,
- RendPostPeriod for posting hidden service descriptors.
Also make sure the hidden service descriptors are at a random
offset from each other, to hinder linkability.

Split logic to initiate dirfetch, running-routers fetch, and
descriptor post. arma: There are some XXXs here that raise design
questions which we should solve before the next release.
The biggest problem is this: Right now, the directory is about 50X as
large as running-routers uncompressed, and about 36X as large
compressed. Assuming:
- everybody gets the compressed version of everything,
- everybody gets cached directories from random dirservers and
uncached r-r from authdirservers
- everybody downloads r-r at the same rate they now download dirs,
then using r-r from will *increase* authdirserver directory bandwidth usage
if there are significantly more caches than authdirservers.
I think it's safe to leave this in for now, since there aren't 3x36 caching
dirservers, but we should make everybody with a dirport cache running-routers
soon. But I could be wrong.
