84f0e87c6a If we have chosen an exit that shares a family with all bridges, fail the circuit 
We could probably do something smarter here, but the situation is
unusual enough that it's okay to just fail the circuit.

ad78bafb71 Correct the behavior of .exit with ExcludeNodes, StrictNodes, etc. 
ExcludeExitNodes foo now means that foo.exit doesn't work.  If
StrictNodes is set, then ExcludeNodes foo also overrides foo.exit.

foo.exit , however, still works even if foo is not listed in ExitNodes.

4851de554d Do not automatically ignore Fast/Stable for exits when ExitNodes is set 
This once maybe made sense when ExitNodes meant "Here are 3 exits;
use them all", but now it more typically means "Here are 3
countries; exit from there."  Using non-Fast/Stable exits created a
potential partitioning opportunity and an annoying stability
problem.

(Don't worry about the case where all of our ExitNodes are non-Fast
or non-Stable: we handle that later in the function by retrying with
need_capacity and need_uptime set to 0.)

7e2e8074d5 slight tweak on circuit_conforms_to_options 
this function really needs to get a total rewrite (or die)

For now, use #if 0 to disable it.

4906188b62 handle excludenodes for dir fetch/post 
If we're picking a random directory node, never pick an excluded one.
But if we've chosen a specific one (or all), allow it unless strictnodes
is set (in which case warn so the user knows it's their fault).

When warning that we won't connect to a strictly excluded node,
log what it was we were trying to do at that node.

When ExcludeNodes is set but StrictNodes is not set, we only use
non-excluded nodes if we can, but fall back to using excluded nodes
if none of those nodes is usable.

Make hidden services more flaky for people who set both ExcludeNodes
and StrictNodes. Not recommended, especially for hidden service operators.

f810a1afe9 Expose a new process_signal(uintptr_t), not signal_callback() 
This is a tweak to the bug2917 fix.  Basically, if we want to simulate
a signal arriving in the controller, we shouldn't have to pretend that
we're Libevent, or depend on how Tor sets up its Libevent callbacks.

6fde2b46d2 Fix more of bug 2704 
The last entry of the *Maxima values in the state file was inflated by a
factor of NUM_SECS_ROLLING_MEASURE (currently 10). This could lead to
a wrong maximum value propagating through the state file history.

3f7f96d9e7 Prevent hugely inflated observed bandwidth values 
When reading the bw history from the state file, we'd add the 900-second
value as traffic that occured during one second. Fix that by adding the
average value to each second.

This bug was present since 0.2.0.5-alpha, but was hidden until
0.2.23-alpha when we started using the saved values.
