the socket module should include `getifaddrs` because it is necessary to translate the output of `if_nameindex` into addresses

Feature or enhancement

Proposal:

socket.if_nameindex, socket.if_nametoindex and socket.if_indextoname all work in terms of interface names and indexes. But in order to do much of use with these values, you need to know what addresses they have, and as far as I can tell the socket module does not provide a means to do so.

This function exists in psutil, in netifaces, and there are various recipes lying around on Stack Overflow and elsewhere for accessing this function.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

未指定源文件或测试。首先检查 socket.if_nameindex、socket.if_nametoindex 和 socket.if_indextoname，然后比较所引用的 psutil 和 netifaces 实现，以确定 getifaddrs 的行为和平台覆盖范围；当 socket 模块能够一致地提供接口地址时即视为完成。
