Major features:
- Make the number of entry guards (and thus, by default, directory
guards too) configurable via a new NumEntryGuards consensus
- Make the number of entry guards configurable via a new
NumEntryGuards consensus parameter, and the number of directory
guards configurable via a new NumDirectoryGuards consensus
parameter. Implements ticket 12688.
