refactoring to use 'gearshift position' instead of uint (AMT) as well as uint and bool (AT) gearboxes. GearList contains ordered list of gears
adapt shift strategies and interfaces.

implementing stop/start functionality for bus aux, refactoring commit simulationstep methd - additional parameters

adding info about TC state to the databus; force line-search for search braking power because interpolate search jumps to a very unreasonable operating point and the whole search and driving action screws up

fix testcases: mock gearbox has to return geearinfo, measured speed / pwheel mode cope with EngineSpeedTooHigh response

adapt testcases due to changed gearbox behavior: no not issue null-requests, use clutch-closed to check if clutch is open or not

 adapt engine tests (idle jump) - clutch no longer accepts null for outSpeed, required info from databus

IdleController: doubleclutch functionality, Gearbox-Databus: TractionInterruption and NextGear now available

adding estimated axle losses (via databus), change gearbox losses to use value from previous state, refactoring of coastingdistance computation (renaming variables)

This reverts commit 41ed08d9.

major refactoring steps done, separation of output data and output writer; VectoCore compiles again, some errors in VectoTest...

driver: limiting acceleration / deceleration
