Re: [PATCH for 8.7.0 00/20] Bump minimum supported qemu version to qemu-4.2 (part 1)

In August Debian 10 officially reaches EOL, thus we can bump minimum qemu version to 4.2 which is being limited by Ubuntu and RHEL/Centos 8. QEMU-4.2 allows us to remove a big bunch of old code though. Few examples which this series (and the next iterations of it) will deal with: - old auidiodev config via ENV variables - old-style VIRTIO tranitional setup (possibly) - most of legacy block device setup (upcoming series) This series is lacking the removal of Debian 10 from our CI infra though, I'll post that separately once I get to it. The patches can also be fetched at: git fetch https://gitlab.com/pipo.sk/libvirt.git debian-10-remove-part1 as some of the pure-removal patches here will be truncated to prevent spamming the list.
