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

由于没有tty，当前的Ctrl-C实现基于uart回调特定函数实现，后续tty实现后
可以重新考虑Ctrl-C设计实现。本次将Ctrl-C移除LOS_MAGIC_KEY_ENABLE，保
证任意情况下可以生效。

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

功能描述：
  在proc目录下增加power目录，添加powr_mode,power_lock,power_unlock和power_count节点，
  power_mode：节点用于查询和设置系统支持的功耗模式
  power_lock：用于查询和获取低功耗锁，持锁后，将会阻止系统进入低功耗状态
  power_unlock:　用于释放已经持有的低功耗锁，也可查询当前有那些持有低功耗锁
  power_count：用于查询当前持有低功耗锁的个数

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。
