And insist that it works.
Drop individual use of xendevicemodel_restrict and
xenforeignmemory_restrict. These are not actually effective in this
version of qemu, because qemu has a large number of fds open onto
various Xen control devices.
The restriction arrangements are still not right, because the
restriction needs to be done very late - after qemu has opened all of
its control fds.
xentoolcore_restrict_all and xentoolcore.h are available in Xen 4.10
and later, only. Provide a compatibility stub. And drop the
compatibility stubs for the old functions.
