9bf9ca4d09 bugfix: add a circ->resolving_streams field, and make dns resolving streams not actually in the connection_array until they're done resolving.
bugfix: actually complain if we duplicate mark-for-close a circuit

add more logging for relay ends that claim dns resolve failed, so we can
find out why they're not being retried.

608c156820 must close marked connections at the end of run_scheduled_events.
otherwise they might have a socket -1, and if we leave them around
they'll muck up poll/select.

i think this was the cause of our win32 and os x fakepoll crashes,
and probably would cause other errors down the road.

505bb2f4a0 it was the second bug that was nailing us.
periodically we expire some circuits if we already have
enough, and we were counting rend circs in that number.

f6dbe5a0d4 Refactor crypto error handling to be more like TLS error handling:
crypto_perror is a no-no, since an operation can set more than one
error.

Also, fix a bug in the unix crypto_seed_rng: mixing stdio with
/dev/urandom is a bad idea, since fopen can make all kinds of weird
extraneous syscalls (mmap, fcntl, stat64, etc.) and since fread tends
to buffer data in big chunks, thus depleting the entropy pool.

The socks handshake is done (it just buffers it).

Tell directory_initiate_command the length of the payload (because
it might include nuls).

Add a directory_has_arrived function to, for example, start building
the rendezvous service descriptor.

47b40de0aa only build circuits after we've fetched the directory
this resolves a subtle bug where tor clients were preferentially using
the directory servers, since when they start building circuits they
know only about the directory servers

on the other hand, it now takes longer after startup before there's
a working circuit. so it goes.
