hls/http/rtmp-play/rtmp-publish load test tool base on st(state-threads), support huge concurrency
服务器负载测试工具SB(SRS Bench)：
- 模拟huge并发：2G内存就可以开300k连接。基于states-threads的协程。
- 支持HLS解析和测试，下载ts片后等待一个切片长度，模拟客户端。支持HLS点播和直播。执行程序：
./objs/sb_hls_load - 支持HTTP负载测试，所有并发重复下载一个http文件。可将80Gbps带宽测试的72Gbps。执行程序：
./objs/sb_http_load - 支持RTMP流播放测试，一个进程支持5k并发。执行程序：
./objs/sb_rtmp_load - 支持RTMP流推流测试，一个进程支持500个并发。执行程序：
./objs/sb_rtmp_publish - RTMP协议使用高性能服务器SRS(SimpleRtmpServer)的协议栈。
注意：
- HTTP/HLS：依赖服务器Content-Length，不支持chunked方式(chunked时会把所有内容当做body一直读)。
- 所有程序都在Linux下运行，模拟客户端运行。
- 其他工具参考srs-librtmp
git clone https://github.com/simple-rtmp-server/srs-bench.git &&
cd srs-bench && ./configure && make &&
./objs/sb_rtmp_load -c 1 -r rtmp://127.0.0.1:1935/live/livestream
TestEnvironment: 24CPU, 80Gbps Network, 16GB Memory
Server: NGINX HLS
Result: 90% bandwith, 72Gbps
