Previously dead peer detection timer was scheduled every dpd_interval, added dpd_interval to all of the clients timestamp and if timestamp was larger than client hearbeat interval * 1.2 then check if client sent some message. If so, flag was reset. This method was source of number of problems so instead different method is now used. Every single client has its own timer with timeout based on (configurable) dpd_interval_coefficient and multiplied with client heartbeat timeout. When message is received from client timer is rescheduled. When timer callback is called (= client doesn't sent message during timeout) then client is disconnected.
