LiteOS2021 04bf3a682f feat: synchronizing arch api 
命名规范：修改少量Arch接口，命名规范化调整：
1.修改arch/include下接口声明，所有arch对外提供调用函数均以ArchXX命名
2.提取多个架构均有实现的公共函数声明至arch/include对应头文件中以供外部调用，并修改命名格式为ArchXX
3.修改OS_HWI_WITH_ARG为LOSCFG_PLATFORM_HWI_WITH_ARG并移至los_config.h中
4.typedef VOID (*OS_TICK_HANDLER)(VOID);暂时移至arch/include/los_timer.h中
5.实现atomic原子操作相关接口，位于arch/include/los_atomic.h,arm架构部分与汇编指令相关原子操作接口使用ARCH_ARM宏进行控制是否编译

BREAKING CHANGE: 1.修改arch/include下接口，以ArchXX命名函数
2.提取公共函数声明:ArchAtomicXchg32bits、ArchAtomicDecRet、ArchAtomicCmpXchg32bits
3.新增部分原子操作c内联实现

kenneth ab886d848a feat: 低内存资源回收low memory killer 
低内存资源回收特性，支持维护可杀低重要任务，当高内存任务申请不到足够内存时，临时释放低重要性的任务来释放内存来满足高内存任务正常运行；
当高内存任务退出运行时，自动恢复被杀的低重要性任务。设计文档归档位置 https://gitee.com/rtos_yuan/lmk/tree/design/

BREAKING CHANGE: 增加低内存资源回收注册相关接口LOS_LmkOpsNodeRegister、LOS_LmkOpsNodeUnregister和内存资源释放和任务恢复接口LOS_LmkTasksKill和LOS_LmkTasksRestore.

LiteOS2021 7b838e8a7b feat: 支持Lms 
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
