* Added auto pointers (std::autor_ptr and home brew TapeDriveAutoPtr) to the
  method castor::vdqm::handler::TapeDriveHandler::newTapeDriveRequest.

* Modified castor::vdqm::IVdqmSvc::selectCompatibilitiesForDriveModel so that
  it no longer allocates a vector of TapeDriveCompatibility on the heap, but
  directly adds the compatibilities it retrieves to the tape drive in question.
