X-ZM-MESSAGEID: 1739976644320019100
From: Jagannathan Raman <jag.raman@oracle.com>
Introduce basic plumbing for vfio-user behind a new
--enable-vfio-user-client option.
We introduce VFIOUserContainer in hw/vfio-user/container.c, which is a
container type for the "IOMMU" type "vfio-iommu-user", and share some
common container code from hw/vfio/container.c.
Add hw/vfio-user/pci.c for instantiating VFIOUserPCIDevice objects,
sharing some common code from hw/vfio/pci.c.
