The timer code used to trigger periodic statistics message sending used ITTI. Together with a high frequency reporting (e.g. 1ms), this resulted in high CPU usage. This commit reimplements this: * using a thread that is synchronized to the RU (if there is no MAC, we assume there is no RU generating a tick so we create the tick source ourselves) * no RB trees but plain arrays * smaller interface for users * slight user interface changes * remove stopped timer state: such timer might be simply removed * remove one-shot timers
