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)

zhangfanfan2 3f71be7535 fix: OsFutexWaitParamCheck函数中absTime为0时，直接返回，不需要打印 
当设置的超时时间比较短时，会出现absTime为0的情况，直接返回，不需要阻塞和打印。

zhushengle 6917e08431 fix: 修改DoNanoSleep 以纳秒为单位 
DoNanoSleep 接口以微秒为单位，纳秒级别的在转换成微秒时被整除为0，
导致转换成tick时为0，导致延时时触发yield，导致延时时间超大

zhushengle 1157c4a289 fix : futex requeue机制中，头节点的queueList 为NULL, 导致系统异常 
queuelist中的普通节点在调整为futexList的节点时，
未校验其queueList的有效性，导致queueList未初始化，
出现访问空指针；且在从旧链表迁移节点到新链表时，
节点从旧链表删除之后又插入到另一个链表中，导致对
旧链表的为NULL判断出错。
