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

  默认只运行smoke测试用例，如需要运行全量测试用例，
请在target_config.h中添加配置项: LOS_KERNEL_TEST_FULL
或在config.json中配置enable_ohos_kernel_liteos_m_test_full

【背景】当前无法使用 trustzone。

【修改方案】
由于tz需要使用svc中断，因此删除之前使用的HalExcSvcCall的地方，改为HalSVCHandler

【影响】
对现有的产品编译不会有影响。

  risc-v架构中，由于执行完mret指令之后，未将mstatus.mpie位清除，
导致锁中断后调度保存上下文信息后, 恢复上下文时误将中断打开。
