zhushengle 0e3936c4f8 feat: 调度相关模块间依赖优化 
背景：
    调度、线程、软件定时器、sortlink、percpu、异常、workqueue模块相互耦合，存在很多不属于本模块的实现，
导致这几个模块间依赖混乱、且到处引用其它模块的内部成员。

方案描述：
    解决上述依赖混乱的问题，为后续调度框架打基础，优化后依赖关系：

                                                              | ---> los_swtmr_pri.h --> workqueue
los_sortlink_pri.h: ---> los_sched_pri.h --> los_task_pri.h -->
   作为基础算法                                               | ---> ipc
(现在为双向链表),
做到功能最小化，
便于后续其它算法替换

调度框架大体方案描述：

1.cpu run queue ----> 任务延时队列

                                         |---- 调度队列
                   |----  EDF        --->
                   |                     |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)
                   |
                   |                     |---- 调度队列
2.task ---> 调度策略----> SCHED_RR   --->
                   |                     |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)
                   |
                   |                     |---- 调度队列
                   |----> SCHED_IDLE --->
                                         |---- 方法(Delay、Suspend、Resume、EntReadyQue、Exit等)

Kiita e1512566e3 fix: 解决dmesg -s参数double lock问题 
【背景】自研shell或者mksh拉起后使用dmesg -s命令出现自旋锁double lock的问题。

【修改方案】
dmesg -s参数设置dmesg缓冲区过程需要访问UartOutput所访问的全局缓冲区，这意味着两个功能模块
使用了同一把自旋锁，若在dmesg命令执行过程使用了打印，则就可能会导致double lock。因此拆分
了dmesg -s命令过程中自旋锁的使用区域，避开内核中必要的打印。

arvinzzz 33d0c1bd0b refactor: 内核目录结构整理 
1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理
2. Kconfig分层，各模块自己的配置放到自己目录下管理
3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理
