libubox
lbubox是openwrt的一个核心库，封装了一系列基础实用功能，主要提供事件循环，二进制格式处理，linux链表实现和一些JSON辅助处理。
它的目的是以动态链接库方式来提供可重用的通用功能，给其他模块提供便利和避免再造轮子。
libubox主要提供三部分功能：
1）提供多种基础通用功能接口，包含链表，平衡二叉树，二进制处理，key-value链表，MD5等。
2）socket通信。
3）一套基于事件驱动的机制及任务队列管理功能。
编译安装到PC
1. 修改目录下CMakelists.txt，先去掉lua部分（不使用lua）。
#OPTION(BUILD_LUA "build Lua plugin" ON) #ADD_SUBDIRECTORY(lua)
2. cmake编译安装
mkdir build; cd build ; cmake .. ; make; make install
