rHG7531cc34713c: urlutil: make `paths` class old list of `path`
Summary

We move from a {name → path} mapping to a {name → [path]} mapping. And
update all user code accordingly. For now, all the list contains exactly one
element, but we are now in a good place to make the config understand a list of
url.
