unify TLP and RTO
...
This doesn't yet implement the persistent congestion detection, since
the specification of that still is in flux.

don't do anything when OnAlarm is called, but no packets are outstanding
...
When all outstanding are acknowledged, the alarm is canceled in
updateLossDetectionAlarm. This doesn't reset the timer in the session
though. When OnAlarm is called, we therefore need to make sure that
there are actually packets outstanding.
