Haryslee 9547133e64 fix：修复llvm编译环境下内核态内存调测调用栈信息解析有误的问题 
背景：内核态内存调测调用栈信息在gcc编译环境下是准确的，但是llvm
编译环境下是错误的，分析知，gcc和llvm编译环境下fp和lr的对应关系
是有区别的。
修复：增加llvm编译环境下对lr解析的逻辑，并用编译宏控制。

qidechun a195aac9fb feat: add blackbox for liteos_a 
1、在内核增加BlackBox核心框架，对外提供模块回调接口注册和故障处理接口。
2、增加默认的系统模块适配层，处理通用内核态和用户态故障日志抓取和保存。
3、BBOX特性默认关闭，若想使用此特性，请在内核配置文件中增加如下编译选项：
LOSCFG_BLACKBOX=y
LOSCFG_SAVE_EXCINFO=y
LOSCFG_SAVE_EXCINFO可以帮助抓取更多的故障日志。
4、若已经打开BBOX特性，想快速验证此特性，请添加如下编译选项：
LOSCFG_HIDUMPER=y

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

Haryslee 9db3407589 feat: 基于汇编实现内核对用户态内存清零的功能 
背景：LOS_UserMemClear接口原有实现是通过在内核中
申请一块堆内存并对其清零，调用copy_to_user来达到
对用户态内存清零的目的，需要使用堆内存。

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
