Nick Mathewson ec8a06c5a1 Require a threshold of exit nodes before building circuits
This mitigates an attack proposed by wanoskarnet, in which all of a
client's bridges collude to restrict the exit nodes that the client
knows about.  Fixes bug 5343.

o Security fixes:
- Only build circuits if we have a sufficient threshold of the total
descriptors marked in the consensus with the "Exit" flag. This
mitigates an attack proposed by wanoskarnet, in which all of a
client's bridges collude to restrict the exit nodes that the
client knows about. Fixes bug 5343.
