Message:

Using dlist in alarm.

Minimal interface changes in alarm.hfa applied; some spill to preemption.cfa occured.

List management logic removed, including such helper functions from alarm.cfa. Remaining logic is concurrency-protection wrapping, and picking insertion point by traversing and comparing alarm-fire times.

Integrity checking definitions removed here. Calling version brought into list.hfa by change 4d741 instead.
