Rob Bradford 2e236c53c8 vfio_user: Implement client side support
Implement (most) of the client side (i.e. VMM side) of the vfio-user
protocol:

https://github.com/nutanix/libvfio-user/blob/master/docs/vfio-user.rst

Items that are not implemented (because they are optimisations or unused
due to alternative solutions:

* VFIO_USER_DMA_READ/WRITE - this is a way for the server to read guest
  memory if the guest memory is not shared by fd where the client
  doesn't support it. However since we do support sharing the memory by
  fd this is not required.
* VFIO_USER_GET_REGION_IO_FDS - an optimisation to bypass the VMM by
  having KVM talk directly to the backend using ioregionfd
* VFIO_USER_DIRTY_PAGES - for the implementation of live migration
