YOUR_NAME 35a2f3af33 fix: init进程收到子进程退出信号后，调用fork重新拉起进程，会导致系统卡死 
问题原因：init进程执行信号时，线程栈底预留了部分空间给信号上下文使用，
从而导致处理信号时线程栈底比线程控制块里面记录的大，这样在fork的过程中内核
从init线程栈底copy线程上下文给新进程时，copy的不是实际运行的栈底，以致于
新进程的线程上下文不对，在实际运行时跑飞，引发系统卡死。
解决方案：在fork过程copy线程上下文时，判断是否预留了信号上下文空间，如果预留
了，则copy的栈底要基于预留后的栈底去copy线程上下文。

zhushengle 1157c4a289 fix : futex requeue机制中，头节点的queueList 为NULL, 导致系统异常 
queuelist中的普通节点在调整为futexList的节点时，
未校验其queueList的有效性，导致queueList未初始化，
出现访问空指针；且在从旧链表迁移节点到新链表时，
节点从旧链表删除之后又插入到另一个链表中，导致对
旧链表的为NULL判断出错。

boxi 4e4f2d6d7e refactor: 对LiteOS_a内核中menuconfig开关的宏使用#ifdef/#ifndef做预编译处理 
LiteOS_a中有部分配置宏进行了重复冗余定义，导致当头文件未被包含时，极易引入错误，
故对menuconfig配置宏进行统一处理，均使用#ifdef/#ifndef作为预编译判断方式

zhushengle cf89f016e9 fix: 解决kill进程时无法保证进程的已持有的内核资源合理释放. 
背景: 当前信号实现原理是在系统调用结束和中断结束时检查是否有信号处理,
      如果有信号处理就切去处理信号，信号处理结束后回来继续按原来流程执行。
问题：当用户态线程在执行系统调用或缺页异常时，运行在内核态，如果此时有信
      号需要处理，且该线程已经持有了部分内核资源(如：锁，内存等), 此时如
      果有中断发生，则在中断结束时，就会去处理该信号，此时用户态线程持有
      了内核未释放的资源跑到了用户态去运行，如果该线程在用户态出现问题,
      那么它持有的内核资源就无法被释放了。
方案：用户态线程在执行系统调用和缺页异常时暂时屏蔽信号，防止此时有中断去
      处理信号，等系统调用结束或缺页异常结束时再去处理信号。
解决的问题：
  1. 执行系统调用或缺页异常时屏蔽信号，防止中断去处理信号
  2.解决无法kill 因为用户态的锁、ipc等阻塞的用户态线程
  3.进程退出方式转变为: 依次通过kill去杀死该进程的所有线程
