httpd 是 Apache HTTP Server 的守护进程名称，Apache HTTP Server 是一种广泛使用的开源网页服务器软件。
本项目是从LwIP中抽取的HTTP服务器代码；
`Hi3861 SDK`中已经包含了一份预编译的lwip，但没有开启HTTP服务器功能（静态库无法修改）；
HTTP 服务器特性
目前已测试通过的功能有：
- 通过HTTP访问静态资源文件
- 通过cgi回调函数处理表单和页面跳转
静态资源文件：
- 本服务器实现不支持实际的服务端本地文件系统访问；
- 取而代之的是，一种简单的虚拟文件系统：
- \\third_party\httpd\src\http\fs.c 文件提供了一套文件系统接口，使用数组直接存储文件数据
- \\third_party\httpd\src\http\fsdata.c文件是由 makefsdata命令生成的虚拟文件系统元数据文件
- makefsdata 命令行工具，用于将一个目录下的静态资源文件转换为 fsdata.c文件
