[Libguestfs] [PATCH 0/5] [RFC] builder: handle unavailable repos

In case a repository of virt-builder references files (e.g. the index) that cannot be downloaded (network issues, 404, etc) then virt-builder errors out on this situation. This is not a nice situation, from an user POV. This series does some refactoring to allow to better handle downloading failures, and handle the failures gracefully in virt-builder. RFC because I'm not yet too convinced the approach I used (especially for the changes in the Curl module) is optimal, so looking for feedback on this.
