J.C. Jones bce88244c0 Bug 1407789 - Prohibit cross-site iframes for Credential Management r=baku,keeler,ttaubert
Credential Management defines a parameter `sameOriginWithAncestors` which is
set true if the responsible document is not either in a top-level browsing
context, or is in a nested context whose heirarchy is all loaded from the
same origin as the top-level context [1][2]. The individual credential types
of CredMan can use this flag to make decisions on whether to error or not.

Our Credential Management implementation right now is a shim to Web
Authentication, which says that if `sameOriginWithAncestors` is false, return
`"NotAllowedError"`.

This ensures that

  https://webauthn.bin.coffee/iframe.html

works, but the cross-origin

  https://u2f.bin.coffee/iframe-webauthn.html

does not.
