详细内容：日志模块，使用宏实现流式输出，支持同步日志与异步日志、自定义日志格式、日志级别、多日志分离等功能。线程模块，封装pthread相关方法，封装常用的锁包括（信号量，读写锁，自旋锁等）。IO协程调度模块，基于ucontext_t实现非对称协程模型，以线程池的方式实现多线程，多协程协同调度，同时依赖epoll实现了事件监听机制。定时器模块，使用最小堆管理定时器，配合IO协程调度模块可以完成基于协程的定时任务调度。hook模块，将同步的系统调用封装成异步操作（accept, recv, send等），配合IO协程调度能够极大的提升服务器性能。Http模块，封装了sokcet常用方法，支持http协议解析，客户端实现连接池发送请求，服务器端实现servlet模式处理客户端请求，支持单Reator多线程，多Reator多线程模式的服务器。
序列化模块
- 序列化模块的底层存储是固定大小的块，以链表形式组织。每次写入数据时，将数据写入到链表最后一个块中，如果最后一个块不足以容纳数据，则分配一个新的块并添加到链表结尾，再写入数据。ByteArray会记录当前的操作位置，每次写入数据时，该操作位置按写入大小往后偏移，如果要读取数据，则必须调用setPosition重新设置当前的操作位置。
- 这样有个好处，不用一开始就开一个很大的空间去存储数据。
1. 主要功能
- 支持序列化固定长度的有符号/无符号8位、16位、32位、64位整数
- 支持序列化不固定长度的有符号/无符号32位、64位整数（使用zigzag算法进行压缩）
- 支持序列化float、double类型
- 支持序列化string和（length+string）的格式
- 支持将序列化内容输出到文件
- 支持大小端转换

3.1 ByteArray
- 序列化类。封装一个内存块，使用链表将内存块连接，实现动态扩容
