Migration with q35 was not possible before commit
04329029a8, because q35
unconditionally creates an ich9-ahci device, that was marked as
unmigratable. So all q35 machine classes before pc-q35-2.4 were
not migratable, so there's no point in keeping compatibility code
for them.
Remove all old pc-q35 machine classes and keep only pc-q35-2.4

In disabled mode, virtio-blk dataplane seems to be enabled, but flow
actually goes through the normal virtio path. This patch simplifies a bit
the handling of disabled mode. In disabled mode, virtio_blk_handle_output
might be called even if s->dataplane is not NULL.
This is a bit tricky, because the current check for s->dataplane will
always trigger, causing a continuous stream of calls to
virtio_blk_data_plane_start. Unfortunately, these calls will not
do anything. To fix this, set the "started" flag even in disabled
mode, and skip virtio_blk_data_plane_start if the started flag is true.
The resulting changes also prepare the code for the next patch, were
virtio-blk dataplane will reuse the same virtio_blk_handle_output function
as "regular" virtio-blk.
Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have
to move s->dataplane->started inside struct VirtIOBlock.

This is needed because dataplane will run during block migration as well.
The block device migration code is quite liberal in taking the iothread
mutex. For simplicity, keep it the same way, even though one could
actually choose between the BQL (for regular BlockDriverStates) and
the AioContext (for dataplane BlockDriverStates). When the block layer
is made fully thread safe, aio_context_acquire shall go away altogether.

For now there are only two dimm's: pc-dimm and nvdimm. This patch is
actually needed to disable ballooning on nvdimm. But, to avoid future
bugs, instead of disallowing nvdimm, we allow only pc-dimm. So, if
someone adds new dimm which should be balloon-able, then this ability
should be explicitly specified here.
Why ballooning for nvdimm should be disabled for now:
NVDIMM for now is planned to use as a backing store for DAX filesystem
in the guest and thus this memory is excluded from guest memory
management and LRUs.
In this case libvirt running QEMU along with configured balloon almost
immediately inflates balloon and effectively kill the guest as
qemu counts nvdimm as part of the ram.
Counting dimm devices as part of the ram for ballooning was started from
commit 463756d03:

The relative ordering of "device_del" return value and the
"DEVICE_DELETED" QMP event depends on the architecture being
tested. On x86 unplugging virtio disks is asynchronous
(=qdev_unplug()= → =hotplug_handler_unplug_request()=) while on s390x
it is synchronous (=qdev_unplug()= → =hotplug_handler_unplug()=). This
leads to the actual output on s390x consistently differing from the
reference output (that was probably produced on x86).
The easiest way to address this is to filter out QMP events in
067. The DEVICE_DELETED event is already getting explicitly tested by
the Python-based test case 139, so the test coverage should be
unaffected. Make use of the recently introduced _filter_qmp_events()
to remove QMP events from the test case output and adjust the
reference output accordingly.
The tr / sed / tr trick used for filtering was suggested by Max Reitz
<mreitz@redhat.com>.
