Haryslee 748e0d8ffb fix: MMU竞态问题修复 
背景：同一个进程的多个线程读写同一个PTE时，由于PTE无保护，存在竞态问题。
方案：新增spinlock保护PTE，包括大锁跟小锁。大锁：一个进程只有一个spinlock锁，多个线程
读写PTE时竞争一把锁，锁的内存占用小，但系统性能降低；小锁：每个页表持有一把spinlock，
由于锁是page结构体的一个字段，内存消耗较大，但是相对大锁性能较优。系统默认使用大锁,用
户可根据具体需要配置使用大锁还是小锁。

zhushengle 298ccea3fe fix: 进程退出前自己回收vmspace中的所有region 
背景：
父进程fork一个子进程，调用waitpid等待子进程结束。
子进程dlopen一个文件a.so，并退出。当守护进程正在
1核回收子进程资源时，父进程在0核运行从waitpid返
回后，同时remove a.so概率失败。

Haryslee 9fdb80f85f fix: 共享内存问题修复 
Signed-off-by: Haryslee <lihao189@huawei.com>
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。

arvinzzz 33d0c1bd0b refactor: 内核目录结构整理 
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

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。

内存完整性校验原有逻辑中当检测到非零异常指针后仍继续访问异常指针
next的内存域导致系统异常。
本次修改后的逻辑为：检测到非零异常指针后直接退出循环，将异常指针
的相关信息输出即可，增加了goto逻辑。对原有功能逻辑无影响。
