tianyifeng 58ff8fa3c2 Add onPreloadError method to PreloadMediaSource.PreloadControl
Upon the call of `PreloadMediaSource.preload`, the source will periodically check the source refresh or period loading error, and trigger `PreloadMediaSource.PreloadControl.onPreloadError`. For now, the `DefaultPreloadManager` will skip the problematic source and continue to preload the next source. The checking of the error will be terminated when the source stops preloading or releases.
