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.

 having a Guard flag or being listed in ExcludeNodes] to render a guard
 "unlisted" (now called "unusable"); track guard down status (now

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.

don't tell you (it happens!); and rotate TLS connections once a week.

1) If an OR conn becomes more than a week old, make it obsolete.
2) If it's obsolete and empty, kill it.
3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
5) When we time out on circuit building on the first hop, make that
   connection obsolete.

f824fb5f83 Bugfix: it looks like some middleman circuits were spending the 
first few moments of their existence in CIRCUIT_STATE_OPEN, then
when Alice sent an extend request for a Tor that they're not connected
to, they switched to CIRCUIT_STATE_OR_WAIT and spent the rest of
their sorry little lives in that state, even when the connection
was established and they were shuttling relay cells back and forth.

And I'm not going to backport this (yet), because somehow it worked!
