New upstream version 1.13.19.
- New tool: virt-sysprep.
- Remove the old guestfish and libguestfs-mount packages, and put these
tools into libguestfs-tools. This change is long overdue, but is also
necessitated by the new virt-sysprep tool. This new tool would pull
in guestfish anyway, so having separate packages makes no sense.
- Remove old obsoletes for virt-cat, virt-df, virt-df2 and virt-inspector,
since those packages existed only in much older Fedora.
