Add code to bulk-sign artifacts
This isn't wired up yet - we need to be able to iterate over AuthFs
directories, but that's coming soon.
Import the OdsignInfo proto, which contains the map of filenames and
digests, and provide a way to build it from a set of artifact files
and write it along with its signature.
Also remove the old Signer trait (which is unused), and a couple of
small refactorings.
