make docker-credential-wincred work like docker-credential-osxkeychain #139

fetch credentials for server with matching hostname if scheme, path, or port are not provided
if the credential request includes specific scheme, path, or port that does not match entry, don't return
extract url helpers into a package

This fixes issues fetching docker credentials in libraries like /~https://github.com/google/go-containerregistry that resolve Docker Hub registry url differently (https://index.docker.io vs https://index.docker.io/v1)

@vdemeester It looks like the Travis build is broken for reasons unrelated to our changes. If that is not a correct diagnosis, let @djoyahoy and I know so we fix it :)

CI is now fixed. Can you rebase ? Thanks

nit: return empty string here instead?

We returned the serverURL here b/c before we made our changes there was never a requirement that the url had to parse successfully (you could still fetch an exact match from the cred store). Happy to change this if you want to make this a requirement.

Oh right read it too fast, you return a nil error. That's fine then 👍

From the documentation: https://golang.org/pkg/strings/#Compare

Compare is included only for symmetry with package bytes. It is usually clearer and always faster to use the built-in string comparison operators ==, <, >, and so on.

So I guess if attr.Keyword == "label" is simpler 😸

You should use bytes.Equal instead.
What is the real type behind attr.Value? Is it an arbitrary byte slice? Or always a string encoded into bytes? My point is: even if the result is the same, I think it's more clearer to cast attr.Value as string instead.

This piece of code existed before our PR so weren't sure if attr.Value needed to be a byte slice for a specific reason, happy to make the changes though.

+	if target, found := findMatch(s, targets, exactMatch); found {


Is this really needed? Can't we just match with approximation? What is the targets length ?

We assumed that if there were both an exact and an approximate match in the cred store, the exact match would be preferable. We can take the exact match out if you disagree.

Sounds good 😄 Ok then 👍
