【背景】
打印有错误单词的提示语
[ERR] Dsipatch signals failed!, ret: 22
这里单词应该是 dispatch 。
【修改方案】
1. 将Dsipatch改为Dispatch。

【影响】
对现有的产品编译不会有影响。

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。

Merge pull request !619 from Caoruihong/opt_make_scripts

【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。

1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理
2. Kconfig分层，各模块自己的配置放到自己目录下管理
3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理

本次提交修复内核加载器，异常情况分支的一个bug：mksh通过exec命令（mksh内置命令
，正常情况下，该命令成功执行会复用mksh进程空间，拉起新的指定进程）。但是如果
进程没有成功加载的情况下，内核加载器的异常分支会错误释放mksh的fd句柄。最终导致
下次拉起其他进程时（fork + exec方式），新的进程会继承fd，映射了早就释放的sysfd
，此时的sysfd可能已经被复用，issue场景下这个sysfd被加载过程中打开的libc.so占用
，exec时会释放procfd->sysfd(错误的映射关系)，最终新进程libc.so被关闭。
导致内核崩溃。

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
