Nick Mathewson 02c320916e Parameterize FRAC_USABLE_NEEDED for fraction of circuits
Instead of hardcoding the minimum fraction of possible paths to 0.6, we
take it from the user, and failing that from the consensus, and
failing that we fall back to 0.6.

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. The default fraction of paths needed is taken from the
consensus directory; you can override it with the new
PathsNeededToBuildCircuits option. Fixes issue 5956.
