some comments on individual patches, but one higher level one here:

the new helpers are mostly used by the catalog shell and by eachother. I think
it would make sense to find or create a more specific place than the catch-all
pbs-client tools. the 'handle_root_with_optional_format_version_prelude' also
seems a bit misplaced there and could maybe move closer to pxar related code as
well?
