Add 5.0 machine types for arm/i440fx/q35/s390x/spapr.
For i440fx and q35, unversioned cpu models are still translated
to -v1; I'll leave changing this (if desired) to the respective

Virtio spec 1.1 (and earlier), 5.2.5.2 Driver Requirements: Device
Initialization:
"Devices SHOULD always offer VIRTIO_BLK_F_FLUSH, and MUST offer it if
they offer VIRTIO_BLK_F_CONFIG_WCE"
Currently F_CONFIG_WCE and F_WCE are not connected to each other.
Qemu will advertise F_CONFIG_WCE if config-wce argument is
set for virtio-blk device. And F_WCE is advertised only if
underlying block backend actually has it's caching enabled.
Fix this by advertising F_WCE if F_CONFIG_WCE is also advertised.
To preserve backwards compatibility with newer machine types make this
behaviour governed by "x-enable-wce-if-config-wce" virtio-blk-device
property and introduce hw_compat_4_2 with new property being off by
default for all machine types <= 4.2 (but don't introduce 4.3
machine type itself yet).

Attempting to migrate a VM using the microvm machine class results in the source

The access to the machine class returned by MACHINE_GET_CLASS() in

This can be resolved by extending the changes in the following commit

Currently, when a notifier is attempted to be registered and its
flags are not supported (especially the MAP one) by the IOMMU MR,
we generally abruptly exit in the IOMMU code. The failure could be
handled more nicely in the caller and especially in the VFIO code.
So let's allow memory_region_register_iommu_notifier() to fail as
well as notify_flag_changed() callback.
All sites implementing the callback are updated. This patch does
not yet remove the exit(1) in the amd_iommu code.

to be added to the PCMachineState structure.
