1.【需求描述】 L0 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】 (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； 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 Close #I41Y9Y Signed-off-by: LiteOS2021 <dinglu@huawei.com>
