 To use Valgrind to detect memory leaks in SRS, even though Valgrind hooks are supported in ST, there are 
 still many false positives. A more reasonable approach is to have Valgrind report incremental memory leaks. 
 This way, global and static variables can be avoided, and detection can be achieved without exiting the

 使用valgrind检测SRS内存泄露时，尽管在ST中支持了valgrind的hook，还是有大量的误报信息。比较合理的是让valgrind报告增量的内存泄露，
 这样可以避开全局和静态变量，也可以不用退出程序就可以实现检测。操作步骤如下：
