Nick Mathewson 813a0f8c40 Compute whether we're ready to build circuits based on fraction of paths
Previously we did this based on the fraction of descriptors we
had. But really, we should be going based on what fraction of paths
we're able to build based on weighted bandwidth, since otherwise a
directory guard or two could make us behave quite oddly.

o Major features:
- When deciding whether we have enough descriptors to build circuits,
instead of looking at raw circuit counts, look at which fraction of
(bandwidth-weighted) paths we're able to build. This approach keeps
clients from building circuits if their paths are likely to stand out
statistically. Fixes issue 5956.
