Gracefully handle deleted packages in analysis Previously, the analysis phase didn't expect any package deletions. So, we'd fail with the error "impossible". But, with the new opam-repository archival process, we allow for deletions, even though only in the special case of a package being archived.

Use opam-ci-check to list reverse dependencies We add an opam pin to install opam-ci-check in the worker running the revdeps listing, and use opam-ci-check to list the reverse dependencies.

Replace Dir_helpers with OpamFilename helpers
