f39bedf250 Implement and document new network liveness algorithm. 
Based on irc discussion with arma.

6700e528be Fix some precision-related asserts in unit tests. 
Mostly by storing the timeout as milliseconds and not seconds
internally.

feccaa5c83 Choose early circuit idle timeout better. 
Don't discard all circuits every MaxCircuitDirtiness, because the
user might legitimately have set that to a very lower number.

Also don't use up all of our idle circuits with testing circuits,
since that defeats the point of preemptive circuits.

e2c2fa7a1f Change liveness value to be a function of the timeout. 
And also the number of recent circuits used to decide
when the network changes.

0352d43917 Move circuitbuildtimeout config check. 
We want it to be under our control so it doesn't mess
up initialization. This is likely the cause for
the bug the previous assert-adding commit (09a75ad) was
trying to address.

Got a negative timeout value on startup. Need to narrow it down.

4b3bc714a3 Woops. Fix a couple memory leaks. 
Also change the max timeout quantile to 0.98, so we can
avoid huge synthetic timeout values.

6eba08e22f Use our variable directly for timeout. 
Using CircuitBuildTimeout is prone to issues with SIGHUP, etc.
Also, shuffle the circuit build times array after loading it
in so that newer measurements don't replace chunks of
similarly timed measurements.

95735e5478 Fix the math.h log() conflict. 
It was compiling, but causing segfaults.

Also, adjust when the timer starts for new test circs
and save state every 25 circuits.

411b60325b Factor out the pretimeout handling code. 
We need to also call it if we're going to calculate alpha
after a normal circuit build.

dc3229313b Teach connection_ap_can_use_exit about Exclude*Nodes 
To further attempt to fix bug 1090, make sure connection_ap_can_use_exit
always returns 0 when the chosen exit router is excluded. This should fix
bug1090.

113ba0e727 make some bug 1090 warnings go away 
When we excluded some Exits, we were sometimes warning the user that we
were going to use the node regardless. Many of those warnings were in
fact bogus, because the relay in question was not used to connect to
the outside world.

Based on patch by Rotor, thanks!

c43859c5c1 Read "circwindow=x" from the consensus and use it 
Tor now reads the "circwindow" parameter out of the consensus,
and uses that value for its circuit package window rather than the
default of 1000 cells. Begins the implementation of proposal 168.
