Don't set unreachable from dirvote unless we've been running a while.
This is a possible fix for bug 1023, where if we vote (or make a v2 consensus networkstatus) right after we come online, we can call rep_hist_note_router_unreachable() on every router we haven't connected to yet, and thereby make all their uptime values reset.

- Don't count one-hop circuits when we're estimating how long it

takes circuits to build on average. Otherwise we'll set our circuit

build timeout lower than we should. Bugfix on 0.2.2.2-alpha.
|

- Directory authorities no longer change their opinion of, or vote on,
|
||||
whether a router is Running, unless they have themselves been online
|

long enough to have some idea. Fix for bug 1023.

o Code simplifications and refactoring:

- Revise our unit tests to use the "tinytest" framework, so we
