Changes to Tf/FastVelo and Tf/PatVelo to make the code thread safe
This are the changes to remove mutable variables giving state to PatVeloSpaceTool and to adapt FastVeloTracking and HitManager to use the new TES object defined in LHCb!516 (merged) rather than the deleted DeVeloSensor::Tell1EventInfo. These two requests should be done together (or the code will not compile).

This should now be compatible with master.
