Several functions need to iterate over the VFIO devices attached to a given container. This is currently achieved by iterating over the groups attached to the container and then over the devices in the group. Let's introduce a per container device list that simplifies this search. Per container list is used in below functions: vfio_devices_all_dirty_tracking vfio_devices_all_device_dirty_tracking vfio_devices_all_running_and_mig_active vfio_devices_dma_logging_stop vfio_devices_dma_logging_start vfio_devices_query_dirty_bitmap This will also ease the migration of IOMMUFD by hiding the group specificity.
