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

1, this RomFS's codebase is Nuttx romfs, then it is compatible with
Linux RomFS and you can create such a file system using the tool genromfs.
2, there are two major changes against with the original Nuttx romfs:
    1), it is memory-based: all contents of the fs are stored in the
        memory in the very first stage of "mount".
    2), this version of romfs is altered to be compatible with our new
        version of VFS to take advantage of vnode cache and path cache.

编译工具链的选项不应该依赖单板的宏，否则每增加一块单板都需要去新增配置。

NULL_ADDRESS_PROTECT这个宏配置没有地方使用，去掉冗余宏，内存是一一映射，可以
访问0地址，且不会立马报错，需要这个功能，现在不是一一映射，而且访问空指针会
立马报错，所以不存在这个问题。
