[webauthn] Merged Pull Request: Describe how authenticators unique and find credential sources.

equalsJeffH has just merged jyasskin's pull request 623 for https://github.com/w3c/webauthn:

== Describe how authenticators unique and find credential sources. ==
This PR builds on #620. Just look at the last commit (50d8d1b) to see what's new here. @leshi, @rlin1, @akshayku, you were cc'ed on https://github.com/w3c/webauthn/pull/602#discussion_r142500439, which this patch implements.

This happens to fix a maybe-bug where the authenticator didn't check that a
decrypted credential ID came from the right RP.

It's also much more precise about the distinction between a credential
descriptor and a credential or credential source.

This still only improves #578, but it makes it clearer where we'll put that fix.
