d6489d8e41 lay a trap for situations where we connection_free something

38be533c69 Handle unavailable hidden services better. We try each intro point
until none are left, then we try to refetch the descriptor. If it's
the same one we had before, then close streams right then. Whenever
a new stream arrives, even if it's right after, optimistically try
refetching the descriptor, just in case.

324b192f68 Make Tor use Niels Provos's libevent instead of it's current
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.

2532e9405e Now we allow writing to the buffer even when the stream if marked for
close, if we're planning to wait to flush it.

This is important because we were sending a socks reject back if we're
closing and hadn't already sent one, but it wasn't actually getting
written since the conn was already marked-for-close.
