MSH中实现TaskKill

常用linux的kill命令,在RTT中没有找到类似的命令,于是自己学习写了一个
依赖库optparse,实现参数解析
可以实现命令结束一个线程
使用方法 `taskkill -n [THREAD_NAME]`

```c
/*
 * Kill a Thread
 * argc = 1 means no arguments
 * USAGE : taskkill -n [THREAD_NAME]
 */
// static const struct optparse_long longopts[] = {{"kill", 'k', OPTPARSE_NONE},{0}};
static void taskkill(int argc, char **argv)
{
 if (argc == 1)
 {
 rt_kprintf(" Missing Arguments!! ");
 rt_kprintf(" Use the taskkill -n [THREAD_NAME] to kill a thread! ");
 }
 else
 {
 rt_thread_t pid = RT_NULL;
 int state = RT_NULL;

// Anaylze the command
 int option = RT_NULL;
 struct optparse options;
 optparse_init(&options, argv);
 while ((option = optparse(&options, "n:")) != -1)
 {
 switch (option)
 {
 case 'n':
 pid = options.optarg ? rt_thread_find(options.optarg) : RT_NULL;
 if (pid == RT_NULL) rt_kprintf(" No Thread Found! ");
 break;
 }
 }
 if (pid != RT_NULL)
 {
 state = rt_thread_delete(pid);
 if (state == RT_EOK)
 rt_kprintf(" Kill Success ");
 else
 rt_kprintf("Kill Failed");
 }
 }
}
MSH_CMD_EXPORT(taskkill, <Use taskkill -n name>)
```

RTT Nano中测试通过
欢迎指正和完善!
