a1e4c6dc85 Fix assertion failure spotted by arma. 
Apparently, when a DNS failure was already cached, then when we tried
to mark the exit connection as closed, we'd try to remove it from the
pending queue anyway, and hit an assert.  Now, we put failed-resolve
connections in a separate state so that mark_for_close does the right
thing.

c5bbb571d2 Refactor mark_for_close, connection_edge_end and friends. Now, everybody 
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.

d508a194f7 Let paranoid exit nodes (which default to reject) be exit nodes 
Before we resolve the hostname, we don't know whether its IP will                        be accepted or rejected by the exit policy of each host. So we                           were only going with nodes that would certainly accept -- which
was just itys and poblano.

(This bug was hidden until now by the earlier port bug.)

(Actual bugfix pending on Nick's next commit, hopefully.)
