Integrate the new "rephist" [rep(utation) hist(ory)] module to trace
...
successful/failed connections, successful/failed extends, and
connection uptimes.
It's still not done: more tests are needed, and not everything calls
connection/circuit_mark_for_close properly. This skews the results.
Also, there needs to be a 'testing' mode for non-OP ORs, where they
periodically build circuits just to test whether extends work.

Refactor mark_for_close, connection_edge_end and friends. Now, everybody
...
who wants to shut down a connection calls connection_mark_for_close instead
of setting marked_for_close to 1. This automatically removes the connection
from the DNS cache if needed, sends a RELAY END cell if appropriate, and can
be changed to do whatever else is needed.
Still to do:
- The same for circuits, maybe.
- Add some kind of hold_connection_open_until_flushed flag, maybe.
- Change stuff that closes connections with return -1 to use mark_for_close,
maybe.
