Check in an implementation of "test" connections from Scott Squires:
 these connections immediately close upon reaching Tor.  They're useful
 for apps that want to check whether they're talking to the same Tor as
 a given controller.  (I'll be tweaking this a bit before I push.)

Add support for (Free?)BSD's natd, which was an old way to let you
 have your firewall automatically redirect traffic.  (Original patch
 from Zajcev Evgeny, updated for 0.1.2.x by tup.)

Have connection_about_to_close use an end_reason field in edge_connection_t to tell what reason to tell the controller for closing the stream.  Set end_reason in connection_edge_end, connection_mark_unattached_ap, and everwhere we set edge_has_sent_end.  Add a changelog entry.

Weasel correctly notes that we should not discard the return value from connection_exit_begin_con.  Right now, the return value is always discardable, so this does not actually cause a bug, but it might later. So fix it.

Fix longstanding bug in connection_exit_begin_conn():  Since connection_edge_end() exits when the connection is unattached, we were never sending RELAY_END cells back for failed RELAY_BEGIN attempts. Fix this.  This might make clients that were otherwise timing out either fail faster or retry faster, which is good news for us.

The otherwise regrettable MIPSpro C compiler warns about values set but never used, and about mixing enums and ints; these are good warnings, and so should be fixed.  This removes some dead code and some potential bugs. Thanks to pnx.

[Needs review.] Add a BEGIN_DIR relay cell type for an easier
 in-protocol way to connect to directory servers through Tor.
 Previously, clients could only connect to director servers over Tor
 from exit nodes, but couldn't get directory information anonymously
 from a non-exit cache without getting a directory server involved.
 
 This needs testing, and needs client-side code to actually exercise it.

d3af1f2189 Backport candidate: Fix a long-standing server-side DNS bug. When a

7239262f71 Don't tell anybody, but we're going OO here. This patch splits
circuit_t into origin_circuit_t and or_circuit_t.  I fixed some
segaults; there may be more.  We still need to move more rendezvous
stuff into subtypes.

This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.

Also, this discards the old HALF_OPEN code, which nobody seems to
want.

892f671f59 Define a schedule for how long to wait between retrying
application connections. Rather than waiting a fixed amount of
time between each retry, we wait only 5 seconds for the first,
10 seconds for the second, and 15 seconds for each retry after
that. Hopefully this will improve the expected experience.

5c57348acd We got an obscure report of an assert error on a windows Tor server with
connection_add being called with socket = -1. The only places I can see
where that happen would be if our tor_socketpair succeeds but it hands
back negative values for some of its file descriptors. Perhaps this will
produce more useful assert errors next time.
