Why use cgo?

[Ryan-Git]

we can't cross-compile recently and find cgo is introduced by #312, but I can't find any ref from or to C, what is it used for?

If you remove cgo, can we compile the code successfully?

@siddontang
yes. on my mac, after removing import "C" from conn.go & resp.go, all builds pass both directly and cross compile to amd64, linux

@Ryan-Git

Can you send me a PR to remove them?

Any reason to add "C" here?

Sure. I'd like to wait one or two days if @michael2008 could reply.

Hi @Ryan-Git , I checked and I think it's a mistake. The import "C" came from nowhere since I did not add it explicitly. Probably it was automatically imported by the IDE. Anyway, my PR should be pure go code and cgo is not needed. You can remove it.
