In the old version, the writePosition would be changed by each new timestep arriving from the rt thread. If the logging of one single timestep would take longer than one loop iteration, this could go on indefinately. Now that local versions of the iterators are used, this should not happend anymore

This reverts commit 6341181b.

new sensorvalue: SensorValueGlobalPositionCorrection and corresponding device GlobalPositionCorrectionSensorDevice

The header is very expensive and is often used in cases where a simple for loop does the exact same thing..
