[rate_ctr] always 'overflow' in next larger inetrval when interval ends
If a second ends, we add the number of events in that just-ended second to the number of events in the currently running minute. The same happens at the end of a minute: We add the number of events in that just-ended minute into the number of events of the still-running hour, etc. This gives a much more meaningful numbers and we don't end up with "12 events per second, but 0 events per minute" kind of situations anymore.
