Refactor UDMI to external repo

[grafnu]

This only contains the substantive changes. There's a bunch of files (pubber/, validator/, schemas/) that need to be deleted, but I'll do that as a separate PR b/c it makes this PR unmanageable (hundreds of changed files). Overall, this PR is functionality neutral.
