For the mirroring system, we need to read out a repository's package archive to know which packages to download. This comes down to reading each desc file in the tarball and outputting the package name and version, and the filename which can be used to download the package. Each of these files can then be queued for download if needed.

The implementation for this would basically be a small wrapper around libarchive's entries where we parse each desc file and output the three values. The parser could therefore be an Iterator returning Option<Result<(String, String, String)>>.
