load contents with cache logic

useful to load contents from slow src input (http for example), load src to local temp file and load it in background thread, use ZFIOCache to config the cache logic

callback's param0 would be the result object if success, param1 would be a ZFResultType indicates load result

the loadImpl's param0 would be a ZFInput points to local cache file or original src, param1 would be the original src input, and should set ZFArgs::result to non null object as result, which would passed to callback
