Steve Sistare	f2f3e4667e	vfio/iommufd: cpr state VFIO iommufd devices will need access to ioas_id, devid, and hwpt_id in new QEMU at realize time, so add them to CPR state. Define CprVFIODevice as the object which holds the state and is serialized to the vmstate file. Define accessors to copy state between VFIODevice and CprVFIODevice.

Steve Sistare	a6f2f9c42f	migration: vfio cpr state hook Define a list of vfio devices in CPR state, in a subsection so that older QEMU can be live updated to this version. However, new QEMU will not be live updateable to old QEMU. This is acceptable because CPR is not yet commonly used, and updates to older versions are unusual. The contents of each device object will be defined by the vfio subsystem in a subsequent patch.

Steve Sistare	06c6a65852	vfio/iommufd: register container for cpr Register a vfio iommufd container and device for CPR, replacing the generic CPR register call with a more specific iommufd register call. Add a blocker if the kernel does not support IOMMU_IOAS_CHANGE_PROCESS. This is mostly boiler plate. The fields to to saved and restored are added in subsequent patches.
