Wiki contradicts godoc with regards to thread-safety about libdns

[znkr]

I think what got me confused is that the client is always called Provider in Go.

Anyway, your suggestion is sound and I am happy to send a PR with the change in the coming days, but I don't mind if someone else changes it.

This is a good point. Yes, I think we strengthened requirements in the godoc more recently than the wiki.

By "provider" we mean the actual remote service. I can't see a use of the term "provider" in the quoted text that means the client implementation. (We use "client implementation" for that.)

But yeah, we should probably clear this up:

• Client implementations (libdns packages) must be thread-safe, i.e. safe for concurrent-use, i.e. no data races.
• Two simultaneous method calls must result in either an error or the expected outcome of each call to be applied successfully.

Maybe we can start with this, I'd love to hear your thoughts on it.

Thanks! Gotcha, yeah some of the early code/comments might be ambiguous since I was still trying to narrow down terminology and stuff.
