利用每次创建时，软件定时器timerId都是唯一的（0~0xffffffff循环），在超时写队列时，同时记录软件定时器id，删除的时候更新软件定时器id，那么在处理软件定时器前，
通过队列中记录的id获取软件定时器控制块，如果控制块的id不等于记录的id，那么说明该软件定时器被删除过，将不执行对应回调函数，表现为删除该定时器。

BREAKING CHANGE: SwtmrHandlerItem结构体新增swtmrID字段，用于标识超时队列中软件定时器id

系统支持newlib，并且可以与musl-C自由切换

1. 新增newlib支持，适配newlib的预留钩子，针对系统能力适配newlib头文件（补充宏定义，结构体定义，posix能力开关），
  采用标准C与自研posix接口声明与结构体定义混合作为C库
2. 梳理kal的依赖关系，kal作为内核对外提供的标准接口，下属包含cmsis、libc、posix。
  cmsis为内核对cmsis接口的支持，libc为内核对三方C库的适配及使用，posix为内核自研提供的posix标准接口。
  若采用musl-C，则kal中选取libc/musl,posix共同作为C库对外支持；
  若采用newlib-C，则kal中选取libc/newlib,部分posix共同作为C库对外支持。
3. fs整理，components/fs下提供基于posix标准的接口改为内部对外接口，供musl以及newlib切换 适配使用

编译选项-fno-short-enums是liteos-m支持kconfig（https://gitee.com/openharmony/kernel_liteos_m/pulls/371）时从Liteos-a核引入的编译选项。添加该编译选项后会输出警告信息，
需要去掉该编译选项。

1.【需求描述】：
   支持内核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】：
   (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

    pm中冻结线程的操作，融合至OsSchedSuspend和OsSchedResume，
使得调度模块提供对应完整的方法给任务模块，做到之间的相互解耦，
方便其它调度算法的融入。
