…nagerMTInit The Service object and the objects from EventSetup must be retrieved in a CMSSW thread.
Using edm::ParameterSet as a global cache feels a bit dirty, but currently it is needed in globalBeginRun. Maybe OscarMTMasterThread object should be the global cache and have some kind of hooks for begin/endRun().
…roducer Because the SimProducers have to register what they produce
…Master() to beginRun()
In order to use it from RunManagerMTWorker
Introduces a memory leak, but avoids a semi-random segfault.

This PR takes first steps towards using Geant4MT in CMSSW. Most modifications are in OscarMTProducer and in new MT-specific classes in order to not interfere with the current OscarProducer. DDDWorld was, however, slightly modified, but the changes should be fine for OscarProducer.
What is implemented:
Changes have been tested such that when splitting the step1 of wf 1.0 to GEN and SIM parts, the SIM job does not crash with OscarMTProducer.
Should not affect regular OscarProducer.
