97c83a4c09 finish enabling begin-dir cells. require one-hop circs for
socks-command-connect-dir streams, so we don't open new anonymity
questions.

0dbf725927 Infrastructure to test BEGIN_DIR cells.
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.

ab68e312bd actually, i think this fix was closest to what i originally
intended. this way we don't call resolve-my-address, which
yells and screams if we're using an internal address (mere
clients should not have to care).

Partial implementation of revised nickname syntax for controllers.  Implement ability to look up routers by "verbose" nicknames; add a per-v1-control-connection flag to turn the feature on in events.  Needs testing, spec, ability to actually turn on the flag, double-checking that we wont overflow any nickname buffers, and changelog.

a3efc8e3d1 - V1 authorities should set "HSAuthoritativeDir 1" to continue being
hidden service authorities too.

  able to remotely teach you about hidden service descriptors. Now
  only accept rendezvous posts if you've got HSAuthoritativeDir set.

9db7b2c068 Allow servers with no hostname or IP address to learn their IP address
by asking the directory authorities. This code only kicks in when you
would normally have exited with a "no address" error.

This design is flawed, though, since the X-Your-Address-Is header is not
authenticated, and doing it this way introduces too many new attacks. The
right answer is to give IP address hints inside the HELLO cell; much of
this code can be reused when we switch.

05d0b70573 Get rid of the router_retry_connections notion. Now routers no longer
try to rebuild long-term connections to directory authorities, and
directory authorities no longer try to rebuild long-term connections to

We still don't hang up connections in these two cases though -- we need
to look at it more carefully to avoid flapping, and we likely need to
wait til 0.1.1.x is obsolete.

474c60b743 Cleanup on time-relaqted constants. New conventions:
1) Surround all constants by (parens), whether we'll be using them
     in a denominator or not.
  2) Express all time periods as products (24*60*60), not as multiplied-out
     constants (86400).
  3) Comments like "(60*60) /* one hour */" are as pointless as comments
     like "c = a + b; /* set c to the sum of a and b */".  Remove them.
  4) All time periods should be #defined constants, not given inline.
  5) All time periods should have doxygen comments.
  6) All time periods, unless specified, are in seconds.  It's not necessary
     to say so.

To summarize, the old (lack of) style would allow:

  #define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
  next_try = now + 3600;

The new style is:

  /** How often do we reattempt foo? */
  #define FOO_RETRY_INTERVAL (60*60)

  next_try = now + RETRY_INTERVAL;

3347c1741d Refactor routerlist access slightly: always use router_get_by_routerlist(); change its interface; add modifier functions to add/remove elements from the current routerlist (so we can add indices).

0d9aedfcea Downgrade a few INFO level logs to DEBUG again. Also add two or three new
logs in cases where a calling function's log was downgraded and we wouldn't
get any log message otherwise.

fd165329b8 start calling it *ListenAddress rather than *BindAddress,
since none of our users know what it means to bind an address or port.

61ea516885 Check for named servers when looking them up by nickname;
warn when we'recalling a non-named server by its nickname;
don't warn twice about the same name.

Fix a bug in routers_update_status_from_networkstatus that made nearly
all clients never update routerinfo_t.is_named.

Try to list MyFamily elements by key, not by nickname.

Only warn about names that we generated ourself, or got from the local
user.

On TLS handshake, only check the other router's nickname against its
expected nickname if is_named is set.

8ae6e1c226 Be more conservative about whether to advertise our dirport.
The main change is to not advertise if we're running at capacity and
either a) we could hibernate or b) our capacity is low and we're using
a default dirport.
