bookmark: use `list_paths` to access path definition The content of the `[paths]` config section is receiving transformation that make it hard to recognise whats the actual name, and the next changeset will make it worse. So we use the official API for this instead. Differential Revision: https://phab.mercurial-scm.org/D10448

urlutil: make `paths` class old list of `path` 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. Differential Revision: https://phab.mercurial-scm.org/D10447

urlutil: extract `chain_path` in a function This will no longer modify `path` inplace so it does not make much sense as a method. Differential Revision: https://phab.mercurial-scm.org/D10446

urlutil: add a `copy` method to `path This will be useful when inheriting from multiple path at the same time. Differential Revision: https://phab.mercurial-scm.org/D10445

template: add a `paths` field to all entry in peerurls This make it possible to display multiple path per name in the near future. Differential Revision: https://phab.mercurial-scm.org/D10444

cache: avoid warming the fnodetags cache after clone That cache can quite expensive to compute on large repository as not that `hg clone` is warming all cache, this can introduces a significant slowdown for clone time[1]. As a stop gap measure introduce a quick fix for that on stable, skipping the fnodetags cache post-clone.
