1. Add live benchmark support in srs-bench, which only connects and disconnects without any media transport, to test source creation and disposal and verify source memory leaks. 2. SmartPtr: Support cleanup of HTTP-FLV stream. Unregister the HTTP-FLV handler for the pattern and clean up the objects and resources. 3. Support benchmarking RTMP/SRT with srs-bench by integrating the gosrt and oryx RTMP libraries. 4. Refine SRT and RTC sources by using a timer to clean up the sources, following the same strategy as the Live source. --------- Co-authored-by: Haibo Chen <495810242@qq.com> Co-authored-by: Jacob Su <suzp1984@gmail.com>
