Of the three possible parameter combinations for
virtio_queue_set_host_notifier_fd_handler:
- assign=true/set_handler=true is only called from
virtio_device_start_ioeventfd
- assign=false/set_handler=false is called from
set_host_notifier_internal but it only does something when
reached from virtio_device_stop_ioeventfd_impl; otherwise
there is no EventNotifier set on qemu_get_aio_context().
- assign=true/set_handler=false is called from
set_host_notifier_internal, but it is not doing anything:
with the new start_ioeventfd and stop_ioeventfd methods,
there is never an EventNotifier set on qemu_get_aio_context()
at this point. This is enforced by the assertion in
virtio_bus_set_host_notifier.

ioeventfd_disabled was the only reason for the default

Now that there is not anymore a switch from the generic ioeventfd handler
to the dataplane handler, virtio_bus_set_host_notifier(assign=true) is
always called with !bus->ioeventfd_started, hence virtio_bus_stop_ioeventfd
does nothing in this case. Move the invocation to vhost.c, which is the
only place that needs it.

Make virtio_device_start_ioeventfd_impl use the same logic as
dataplane to set up the host notifier. This removes the need
for the set_handler argument in set_host_notifier_internal.
This is a first step towards using virtio_bus_set_host_notifier
as the sole entry point to set up ioeventfds. At least now
the functions have the same interface, but they still differ
in that virtio_bus_set_host_notifier sets ioeventfd_disabled.

This simplifies the code and removes the ioeventfd_started
and ioeventfd_set_started callback. The only difference is
in how virtio-ccw handles an error---it doesn't disable
ioeventfd forever anymore. It was the only backend to do
so, and if desired this behavior should be implemented in
virtio-bus.c.
Instead of ioeventfd_started, the ioeventfd_assign callback now
determines whether the virtio bus supports host notifiers.

Highlights:
* SLOF (pseries guest firmware) update
* Enable a number of extra testcases on ppc / pseries
* Added the 'powernv' machine type
- Almost enough to be minimally usable
- But still missing necessary interrupt controller updates
* Cleanup and consolidation of NVRAM handling on several platforms
with related firmware
* Substantial cleanup to device tree construction
* Some more POWER9 instruction emulation
* Cleanup to handling of pseries option vectors and CAS reboot
handling (host/guest feature negotiation mechanism)
* Significant cleanups to handling of PCI devices in test cases
* New hotplug event infrastructure
* Memory hot unplug support for pseries
* Several bug fixes
The NVRAM cleanup affects some Sun sparc platforms as well as ppc
ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).
The test additions also include substantial general changes to the
test framework that aren't strictly ppc related. They don't seem to
break tests on other platforms, they're for the benefit of enabling
tests on ppc and there isn't a specific maintainer for them, so
they're included in this tree.

ppc hypervisors have delivered system reset and machine check exception
interrupts to guests in some situations (e.g., see FWNMI feature of LoPAPR,
or NMI injection in QEMU).
These exceptions are architected to set the HV bit in hardware, however
when injected into a guest, the HV bit should be cleared. Current code
masks off the HV bit before setting the new MSR, however this happens after
the interrupt delivery model has calculated delivery mode for the exception.
This can result in the guest's MSR LE bit being lost.
Account for this in the exception handler and don't set HV bit for guest
delivery.
Also add another sanity check to ensure similar bugs get caught.
