    test-application.c: Install a signal handler to exit cleanly
    
    The app-test program gets run by atk_test_util.c, and gets sent a
    SIGTERM when the parent process wants it to terminate.  This is fine,
    but if app-test terminates forcefully with the default handler for
    SIGTERM, then libgcc won't get a chance to write out its code coverage
    information.
    
    So, we install a signal handler for SIGTERM, and the handler exits the
    main loop.
