Give sensible feedback when a repo has no configured servers
This fixes FS#14899. When running an -Sp operation without servers configured for a repository, we would segfault, so add an assert to the backend method returning the first server preventing a null pointer dereference. In addition, add a new error code to libalpm that indicates we have no servers configured for a repository. This makes -Sy and -S <package> operations fail gracefully and helpfully when a repo is set up with no servers, as the default mirrorlist in Arch is provided this way.
