Merge pull request !645 from SimonLi/OpenHarmony-3.0-LTS

【背景】
1. liteos-a内核drivers/mtd/multi_partition/用到了device/hisilicon下的驱动函数实
现，这样导致三方芯片适配时，会依赖hisilicon的驱动。
2. HDF的mtd驱动提供了这几个函数的实现，但是未暴露头文件出来。

【修改方案】
1. 修改BUILD.gn去除/device/hisilicon的依赖。
2. 修改mtd_partition.c，将hisilicon的头文件改为hdf的头文件依赖。

【遗留问题】
liteos-a内核与HDF mtd驱动的分界线还不明确，导致依赖关系不清楚

fix: 共享内存问题修复
Signed-off-by: NHaryslee <lihao189@huawei.com>
背景：父进程移除共享内存并标记SHM_SEG_REMOVE,当子进程资源回收时在
ShmFindSeg接口中判断该共享内存具有SHM_SEG_REMOVE时返回空，但是此时
seg->ds.shm_nattch不为0，不应返回空。
方案：ShmFindSeg接口中增加seg->ds.shm_nattch为0的判断。

【背景】
集成测试发送两个不同的信号，sigwait第二次等到的仍是第一个信号
经定位，信号在kill时会将相关的siginfo信息拷贝到taskcb的unbinfo中，sigwait
处理时从unbinfo拷贝给用户。若此信号发送时处于屏蔽状态，再有其他信号发送会覆盖
掉unbinfo，此时sigwait等待这个信号获取到的info已经被覆盖
【修改方案】
1. 每个任务添加一个siginfo缓存链表，在处理信号前夕从缓存链表取出info到unbinfo中

【影响】
对现有的产品编译不会有影响。

You can specify another config file in hb build like this:
  hb build --gn-args liteos_config_file=myconfig.config
file specified in liteos_config_file argument is relative
to "$product_path/kernel_configs" directory, or is an
absolute file path, for example:
  hb build --gn-args liteos_config_file=//path/to/myconfig.config
or
  hb build --gn-args liteos_config_file=/another/path/to/myconfig.config

        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
