2023-03-07hw/xen: Implement soft reset for emulated gnttabDavid Woodhouse
This is only part of it; we will also need to get the PV back end drivers to tear down their own mappings (or do it for them, but they kind of need to stop using the pointers too). Some more work on the actual PV back ends and xen-bus code is going to be needed to really make soft reset and migration fully functional, and this part is the basis for that.
