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.

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
