mcpu: Use new timeout class for timeout
mcpu: Change lock attempt timeout calculation
With this patch all timeouts are pre-calculated. The interface ofthe _LockTimeoutStrategy class is also changed a bit; NextAttemptnow returns a new instance.
mcpu: Implement lock timeouts
The timeout is always between ~0.1 and ~10.0 seconds. A smallvariation of ±5% is added to prevent different jobs fromfighting each other. After 10 attempts to acquire the locks witha timeout, a blocking acquire is made.
Lock status reporting will be improved in a separate patch....
