net: `Resolver.resolveAddrList()` should be public

[AlmogBaku]

Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

master

What did you expect to see?

This function is very useful therefore it should be public.

What did you see instead?

Resolver.resolveAddrList() is private

Being subjectively useful to one person is not the bar for making something public.

If you want to push this forward, please go through the proposal process (https://golang.org/s/proposal) and file a new bug with a more substantive proposal and try to quantify the benefit and that it outweighs the costs of extra API bloat & docs. Approximately how many existing users in the Github corpus would benefit? Which existing bugs would this fix? What features would this enable?

Anything more than "is very useful [to me] therefore it should be public".

I'm going to close this for now, but feel free to reply or file a new issue if you collect more data.
