This is a preparatory series for the switch to -blockdev with Proxmox
VE 9, QEMU machine version 10.0, based in part on Alexandre's series
here [0].
While the last patch actually does the switch, many operations are not
yet supported. It is included to show what changes I made there. It
should not yet be applied and supporting everything is the goal for a
following series based on the rest of Alexandre's patches. It was time
to send this however, as it's already gotten large enough (but most
patches are quite small, so don't worry reviewers ;)).
There are mostly cleanups, moving and defining helpers, as well as
doing non-intrusive preparation for the switch with machine version
10.0. Quite a large chunk of the series is for having
activate_volumes() be called before config_to_command() with proper
cleanup handling.
A breaking change is the removal of the gone-since-QEMU-3.1 drive
geometry options. It was not possible to even start or backup a VM
with those options set since then. Still, restore of old backups with
such an option is made explicitly supported.
