Guangyao Ma 5a80d4e1a3 fix: solve SIGCHLD ignored in sigsuspend() 
在如下场景signal可能得不到及时处理：
1、进程A设置信号a阻塞
2、进程A收到信号a
3、进程A调用sigsuspend结束阻塞
原则上，步骤三应该立刻处理之前被阻塞的信号a，调用信号处理函数，并且sigsuspend
返回。现在的问题是，信号a没有得到及时处理，并且进程A阻塞在sigsuspend()调用流程
。
本次修改，在1、2、3场景下，sigsuspend()处理过程中，如果发现已经收到信号，待处理
时，会立刻进行调度切换，再次调度回来时，在调度模块中，会先主动处理已经收到的信
号，最后sigsuspend返回用户态。

zhushengle 67ac8c4c58 fix: 以g_sysSchedStartTime是否为0判断时间轴是否生效存在极限场景导致调度时间不生效 
初始化调度时间不以g_sysSchedStartTime是否为0为界限，而以g_sysSchedStartTime是否为64位最大值
为界限，避免特殊以下场景：调度开启时系统时间为0，导致初始化的g_sysSchedStartTime还是0，导致
调度启动后获取的调度时间轴始终为0.

Guangyao Ma 27dca4d857 feat(vfs): vfs支持FD_CLOEXEC标记 
首先，POSIX规范规定文件描述符需要支持close-on-exec属性，修改前的vfs不支持close-on-exec，当exec系列函数执行时，进程所有的文件将会被关闭（0，1，2也重新被打开）。但是，系统有些时候是不能在exec时关闭全部文件的，例如在执行exec之前，就需要重定向进程的某些文件描述符时（使用dup2），就希望该文件不被关闭，继续保持重定向属性，shell执行进程并重定向其标准输出到文件，这是我们经常做的事情。

BREAKING CHANGE:
执行exec类函数后，进程拥有的文件描述符情况发生变化：修改前，默认关闭所有的进程文件描述符，0，1，2重新打开；修改后，除非文件描述符拥有FD_CLOEXEC标记，否则该描述符不会被关闭。

Haryslee 42f374dd7a fix: 合并进程栈两个地址连续的region 
背景：进程加载的时候，先预申请一个页用作参数拷贝，另外通过mmap方式申请
额外的虚拟栈空间，此时便有两个地址连续的区间。
方案：新增内部接口OsStackAlloc，用于申请一个连续的虚拟地址区间，并对其
中指定区间做物理内存的映射。

zhushengle 8df3e8c965 fix: tick 动态化计算优化，消除中断执行时间对系统总体时间的影响，保证软件定时器的响应精度。 
方案描述：
    1.周期软件定时器超时添加一个startTime字段，用于记录当前软件定时器的开始计时的时间，
    在定时器响应时，开始时间修改为上一次响应的结束时间(消除了中断执行时间对软件定时器
    的影响)。
    2.在执行tick中断的过程当中，持有tick动态计算锁，保证在该过程中不会触发tick周期
    的计算，在tick中断结束时统一计算设置。 --- 提升tick中断的执行效率
    3.在设置tick周期时，减掉tick中断执行的时间，减小周期动态化带来的时间误差
    4.新增LOSCFG_BASE_CORE_TICK_PER_SECOND_MINI配置宏，用于配置tick中断的最小响应精度

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。

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 7de43bb004 fix: 修复kill进程时，因liteipc阻塞的进程概率无法退出问题 
kill进程时，会将因为liteipc阻塞的线程唤醒，使其调度并自动退出，由于liteipc阻塞机制为
循环阻塞方式，会导致将因liteipc阻塞的线程唤醒后又进入等待中。此处在唤醒因liteipc阻塞的
线程后检查是否已有kill标志，如果有使其按接收数据失败退出，在返回用户态之前，该线程会进
入退出流程，结束运行。

Kiita e5f6bf0556 feat: timer_create支持以SIGEV_THREAD方式创建定时器 
【背景】当前timer_create接口不支持以SIGEV_THREAD的方式创建多个定时器

【修改方案】
1、内核timer_create接口在创建software timers相应的线程时，使用线程
taskCB所携带的信息识别各个线程的信号并依据该信息分别派发出信号。
2、关于用户任务操作许可验证的修改，现在允许同一用户线程向其自身派发信
号，软件定时器计时结束，向用户态发送相应的信号，完成用户态线程的回调。

【影响】
对现有的产品暂无影响。

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
