方案描述：
   和L0保持一致，上层通过proc文件系统操作：
   power_mode  支持的低功耗模式，通过对该文件进行write操作可以设置低功耗模式
   power_count powermanager模块通过对该文件操作，和内核进行交互，简要流程如下：
     while (1) {
       open  // 打开该文件
       read  // 使powermanager低功耗任务常阻塞，当系统无任何模块持锁时，会唤醒该任务
       write // 进行低功耗流程
       close // 关闭该文件
     }
   power_lock    write该文件，持锁
   power_unlock  writw该文件，释放锁

1.【需求描述】：
   支持内核态和用户态堆内存非法访问检测，包括：越界访问、double free、释放后使用；支持libc常用高频函数内存检测；支持安全函数内存检测；读写检测可配可裁剪。
2.【方案描述】：
   L0 ~ L1:
   (1).影子内存映射与标记
   (2).编译器使能-fsanitize=kernel-address 自动插桩检测点
   (3).实时校验影子内存的合法性；
   (4).错误访问打印回溯栈

BREAKING CHANGE: 新增支持API:

LOS_LmsCheckPoolAdd使能检测指定内存池
LOS_LmsCheckPoolDel不检测指定内存池
LOS_LmsAddrProtect为指定内存段上锁，不允许访问
LOS_LmsAddrDisableProtect去能指定内存段的访问保护
