Title: Fixed PPM, DSM and S.Bus co-existence, tested S.Bus

This patch introduces co-existence of the different input methods with respect of the joint channel data structure. If multiple input sources are present, S.Bus has highest priority, then DSM, then PPM. The availability of different sources is correctly accounted in any case, just the channel values and timestamps are stored according to this order.

This has been successfully tested with S.Bus input and FMU / QGroundControl.
