        1.【需求描述】
            L0~L1 支持Trace，提供两种工作模式：在线模式、离线缓存模式， 用于按时间线追踪系统事件，如任务切换、中断、ipc等。
        2.【方案描述】
            L0:
            (1).在内核模块预置静态代码桩
            (2).触发桩后，收集系统上下文信息
            (3).离线模式则写入内存，用户可通过dump导出；
            (4).在线模式通过pipeline对接IDE进行可视化解析和展示；
            L1:
            新增trace字符设备，位于"/dev/trace",通过对设备节点的read\write\ioctl，实现用户态trace；

        BREAKING CHANGE:
        1.新增一系列trace的对外API，位于los_trace.h中.
        LOS_TRACE_EASY简易插桩
        LOS_TRACE标准插桩
        LOS_TraceInit配置Trace缓冲区的地址和大小
        LOS_TraceStart开启事件记录
        LOS_TraceStop停止事件记录
        LOS_TraceRecordDump输出Trace缓冲区数据
        LOS_TraceRecordGet获取Trace缓冲区的首地址
        LOS_TraceReset清除Trace缓冲区中的事件
        LOS_TraceEventMaskSet设置事件掩码，仅记录某些模块的事件
        LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数

方案描述：
    1.周期软件定时器超时添加一个startTime字段，用于记录当前软件定时器的开始计时的时间，
    在定时器响应时，开始时间修改为上一次响应的结束时间(消除了中断执行时间对软件定时器
    的影响)。
    2.在执行tick中断的过程当中，持有tick动态计算锁，保证在该过程中不会触发tick周期
    的计算，在tick中断结束时统一计算设置。 --- 提升tick中断的执行效率
    3.在设置tick周期时，减掉tick中断执行的时间，减小周期动态化带来的时间误差
    4.新增LOSCFG_BASE_CORE_TICK_PER_SECOND_MINI配置宏，用于配置tick中断的最小响应精度

之前修改窗口宽度，为了适配流水线。流水线已经完成自适应，建议回退回80宽度。一方
面，shell显示更友好。一方面，在tty完成前，也没有更好的处理方法。

LiteOS_a中有部分配置宏进行了重复冗余定义，导致当头文件未被包含时，极易引入错误，
故对menuconfig配置宏进行统一处理，均使用#ifdef/#ifndef作为预编译判断方式
