Round up a couple of outstanding fixes, add console support and fix up
per-vCPU upcall vector support (which was previously untested), and that
allows us to boot PV guests. Document it.
Having fixed up the per-vCPU upcall vector support, pull in slightly
newer Xen headers just for the definition of the CPUID bit that lets
us tell the Linux (6.0+) kernel to use it. That'll help with testing.
v2 of this series falls down the rabbithole a little more...
Now I know how to convert drivers to the "new" XenDevice model, let's do
so for the Xen PV network driver, which has been on the TODO list for a
while. Fix that up for actual Xen PV guests too (-m xenfv) because
that's hosed right now even before the conversion.
Fix up net_cleanup() so it doesn't free the NICs from underneath the
device models which own them.
Switch the avocado test to use the Xen PV network device too.
Simplify the user experience for "-device file=IMAGE,if=xen" because
that was offending me.
Update the documentation, and take the opportunity to fix up that bit
about unplug not working on Q35, because I worked out how to do that
when heckling Joel's attempt to do so.
