背景：
父进程fork一个子进程，调用waitpid等待子进程结束。
子进程dlopen一个文件a.so，并退出。当守护进程正在
1核回收子进程资源时，父进程在0核运行从waitpid返
回后，同时remove a.so概率失败。

背景：进程加载的时候，先预申请一个页用作参数拷贝，另外通过mmap方式申请
额外的虚拟栈空间，此时便有两个地址连续的区间。
方案：新增内部接口OsStackAlloc，用于申请一个连续的虚拟地址区间，并对其
中指定区间做物理内存的映射。

内存完整性校验原有逻辑中当检测到非零异常指针后仍继续访问异常指针
next的内存域导致系统异常。
本次修改后的逻辑为：检测到非零异常指针后直接退出循环，将异常指针
的相关信息输出即可，增加了goto逻辑。对原有功能逻辑无影响。
