typically the resolve will be pending, but it could be failed if it
just failed and we're working through the 'pending' list, or it could
be valid if some other dnsworker raced us to fill in the entry.

who wants to shut down a connection calls connection_mark_for_close instead
of setting marked_for_close to 1. This automatically removes the connection
from the DNS cache if needed, sends a RELAY END cell if appropriate, and can
be changed to do whatever else is needed.
Still to do:
- The same for circuits, maybe.
- Add some kind of hold_connection_open_until_flushed flag, maybe.
- Change stuff that closes connections with return -1 to use mark_for_close,
maybe.

We were telling a child to die by closing the parent's file descriptor
to him. But newer children were inheriting the open file descriptor from
the parent, and since they weren't closing them, the socket never closed,
so the child never read eof, so he never knew to exit.
As a side effect to this bug, we were probably failing to properly close
connections to remote hosts, ORs, and OPs, after a dns child was born.
I'm surprised Tor worked at all.

not when we're closing the stream.
this lets us put a payload in the end cell if we want to,
to describe why we're closing the stream.
there are still some places where we don't send the end cell
immediately. i need to track them down. but it's a low priority,
since i've made it send the end cell when we close the stream if
we haven't already sent it.

ERR is if something fatal just happened
WARNING is something bad happened, but we're still running. The bad thing
is either a bug in the code, an attack or buggy protocol/implementation
of the remote peer, etc. The operator should examine the bad thing and
try to correct it.
(No error or warning messages should be expected. I expect most people
to run on -l warning eventually.)
NOTICE is never ever used.
INFO means something happened (maybe bad, maybe ok), but there's nothing
you need to (or can) do about it.
DEBUG is for everything louder than INFO.

'buf_t' is now an opaque type defined in buffers.c .
Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors. Descriptors are now self-signed.
Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.
At least "routers.or" and orkeygen are now obsolete, BTW.
