    easy_events: make event data static
    
    First: this function is only used in debug-builds and not in
    release/real builds. It is used to drive tests using the event-based
    API.
    
    A pointer to the local struct is passed to CURLMOPT_TIMERDATA, but the
    CURLMOPT_TIMERFUNCTION calback can in fact be called even after this
    funtion returns, namely when curl_multi_remove_handle() is called.
