Completely ignore abandoned circs from circ timeout calc
7fc4460 
This prevents the timeout curve from getting spread out as much, resulting in
more accurate timeout values for quantiles from 60-80.
Lower min circ timeout from 1.5s to bin width (10ms)
1d5f83b
Raise the circuit close time quantile to 99.
6c68f1f 
This should allow us to more accurately estimate pareto parameters
without relying on "right-censorship" of circuit build timeout values.
Log circuit timeout in milliseconds
f410936
Lower circuit build time bin width to 10ms.
b9e3b98 
50ms is not enough resolution. CBT can be as low as 80ms in datacenter
clients close to their relays.
Fix Xm mode calculation to properly average N=10 modes.
88fa853 
This is still fast enough. ~100usec on my laptop with 1000 build times.

Bug 34088: Remove max timeout calculation and warning.
960a859 
With the maximum likelihood estimator for alpha from #40168, we no longer need
max_time to calculate alpha.
