Export END_CIRC_REASON_* to controller?

[Mike Perry]

Hey guys,

I'm working on an update to the Snakes On A Tor scanner (still in
perl, unfortunately), and I would like to gather statistics on circuit
failure rates for nodes.

Is it possible to sneak in a "REASON" field into the tor control spec
for CIRC CLOSED events? It would be useful to be able to tell which
circuits were cleaned up by Tor and which may have been dropped due to
unstable or malicious nodes.
