b0fc18c37e Changes from Nick's code review 'part 1' 
I think this is actually his third code review of this branch so far.

ccaeef22e1 Tags on relay cells can result in certain reason codes. 
Close the circuit (it's probably junk anyways), and make sure we don't probe
it/count it as a success.

b75880d7b3 Fix a rather serious use-count state bug. 
We need to use the success count or the use count depending on the consensus
parameter.

2dbb62f1b5 Convert to doubles for all pathbias state. 
Let's hope this solves the rounding error issue..

ab1fce5c19 Also shorten circuit_successes to circ_successes. 
For consistency and great justice.

Ok, mostly consistency.

a90f165b83 Rename first_hop to circ_attempt. 
Since we've generalized what we can count from (first or second hop), we
should generalize the variable and constant naming too.

Mike Perry
04866055e8 Change from first hop accounting to 2nd hop accounting 
This has several advantages, including more resilience to ambient failure.

I still need to rename all the first_hop vars tho.. Saving that for a separate
commit.

Cpath is apparently good enough.

7f8cbe389d Fix a crash due to NULL circ->n_chan. 
Is this redundant? Can we always rely on circ->cpath->extend_info
being present for origin circuits?

412ae099cb Prop 209: Add path bias counts for timeouts and other mechanisms. 
Turns out there's more than one way to block a tagged circuit.

This seems to successfully handle all of the normal exit circuits. Hidden
services need additional tweaks, still.
