[Needs review.] Add a BEGIN_DIR relay cell type for an easier
in-protocol way to connect to directory servers through Tor.
Previously, clients could only connect to director servers over Tor
from exit nodes, but couldn't get directory information anonymously
from a non-exit cache without getting a directory server involved.
This needs testing, and needs client-side code to actually exercise it.
