Make data checksums launcher cancel its worker at SIGINT Make sure the launcher cancels the currently running worker by calling TerminateBackgroundWorker when it receives SIGINT. In order to handle cases where SIGINT arrives while tje launcher is waiting for a worker to start or exit, implement a version of WaitForBackgroundWorkerStartup and WaitForBackgroundWorkerShutdown which checks the abort_requested signalling. A new test which kills processing with SIGINT is added.
