In this patch we now make use of the new RtpTimerQueue instead of the old GArray. This required a lot of changes all over the place, some of the important changes are that `timer->timeout` is no longer a PTS but the actual timeout. This was required to get the RtpTimerQueue sorting right. The applied offset is saved as `timer->offset`, this allow retreiving back the PTS when needed. The clockid updates only happens once per incoming packet. If the currently schedule timer is before the earliest timer in the queue, we no longer wakeup the thread. This way, if other timers get setup in the meantime, this will reduce the number of wakup. The timer loop code has been mostly rewritten, though the behaviour of running the lost timers first has been kept (even though there is no test to show what would be the side effect of doing this differently). Fixes #608
