Mr @douzzer is working on a way to track the bytes protected by a given key for the streaming service APIs and will push an update to this PR when ready.

See #7560 -- the API change for AES-XTS-stream to support this req wound up having the customary mushrooming impact on the related test+shim code, so I put it up as its own PR that supersedes this one.

Thanks @kaleb-himes for driving visiblity around the SP800-38E req!
