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.)

c485725c5a Fix the dns bug: children weren't dying 
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.

9a676b04dd Check that we can write to the logfile and log a warning to stderr if we can't 
Move writing of pidfile after daemonizing, and also after setting the [ug]id:
This means that the tor user needs write priviliges to the pidfile location.
It needs it for unlinking the pidfile anyway.

f0cccc567e bugfix: don't ask for ->next of an expired circuit 
bugfix: keep going when a circ fails in circuit_n_conn_open
        (make circuit_enumerate_by_naddr_nport obsolete)
bugfix: make circuit_n_conn_open only look at circ's that start at us
bugfix: only try circuit_n_conn_open if we're an OP. Otherwise we
        expect connections to always already be up.
bugfix: when choosing path length, pay attention to whether the directory
        says a router is down.
bugfix: when picking good exit, skip routers which are known to be down
        (more work needs to be done on this one)

a8eaa79e03 Improved exit policy syntax; basic client-side DNS caching. 
- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts
  18.0.0.0/8.  Policies are parsed on startup, not when comparing to them.

- desired_path_len is now part of an opaque cpath_build_state_t structure.

- END_REASON_EXITPOLICY cells no longer include a port.

- RELAY_COMMAND_CONNECTED cells now include the IP address we've connected
  to.

- connection_edge now has a client_dns cache to remember resolved addresses.
  It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY
  cells.  It gets used by connection_ap_handshake_send_begin.  We don't
  compare it to exit policies yet.
