In concrete terms, for the timer library, I'm mostly suggesting that
TransformAlarmC be replaced by a "TransformAlarmCounterC"
(TransformCounterC should stay for h/w timers not used for alarms). Of
course we can leave TransformAlarmC too, it's just that at some point
we should avoid too much duplicate code and too many options...
