* fhandler_socket.cc (fhandler_socket::create_secret_event): Avoid
        creating multiple handles. Always allow event inheritance but set the
        handle inheritance appropriately. Improve error handling.
        (fhandler_socket::check_peer_secret_event): Improve error handling.
        (fhandler_socket::close_secret_event): Simply call CloseHandle.
        (fhandler_socket::set_close_on_exec): Set secret event inheritance.
