[Libguestfs] [v2v PATCH 0/9] generate virtio-transitional devices if told so by libosinfo

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1942325 The first part of the series introduces the "gcaps_virtio_1_0" guest capability (default value, according to the current virt-v2v assumption: "true"), and updates the libvirt and JSON outputs to take the new capability into account. In the libvirt output, the virtio device models are flipped to -- or are explicitly introduced as -- virtio-transitional if the machine type is Q35 and the new "gcaps_virtio_1_0" capability is "false". In the JSON output, we don't change any device models, only expose the new capability, and allow CNV / KubeVirt to act upon it. This follows the spirit of <https://bugzilla.redhat.com/show_bug.cgi?id=1942325#c11>;. The second part of the series wraps the osinfo_os_get_all_devices() libosinfo API, and introduces a dependent function to retrieve the guest OS's support for each of the Q35 chipset and the virtio-1.0 protocol (extrapolated from support for virtio1.0-net), from the osinfo database. The final patch in the series couples the two previous parts. The Notes section of this patch contains extensive test results.
