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)
