These are very much like the sample configuration files
for q35, and can be used both as documentation and as
a starting point for creating your own guest.
Two sample configuration files are provided:
* mach-virt-graphical.cfg can be used to start a
fully-featured (USB, graphical console, etc.)
guest that uses VirtIO devices;
* mach-virt-serial.cfg is similar but has a minimal
set of devices and uses the serial console.
All configuration files are fully commented and neatly
organized.

Instead of having a single sample configuration file,
we now have several:
* q35-emulated.cfg documents the default devices QEMU
adds to a q35 guest and the additional devices that
are pretty much guaranteed to be present in a
physical q35-based machine;
* q35-virtio-graphical.cfg can be used to start a
fully-featured (USB, graphical console, audio, etc.)
guest that uses VirtIO instead of emulated devices;
* q35-virtio-serial.cfg is similar but has a minimal
set of devices and uses the serial console.

Apparently, none of the bus owner give a reference to the hotplug
handler property, do not unref it on bus release.
Furthermore, a bus is allowed to be its own hotplug handler, which can
be seen in qbus_set_bus_hotplug_handler() function. However, in this
case, the reference can't be given to the property, or this will create
a cyclic dependency and the bus will never be free.
Each bus owner should manage the lifecycle of the hotplug handler.

PCI hotplug for bridges was introduced only since 2.0 however
acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL)
didn't take in account that for legacy mode (1.7) when
PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property
the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time.
We managed to live with it only because of error rised by adding
a duplicate property in acpi_set_bsel() has been ignored which
resulted in useless leaking of just allocated (int)bus_bsel.
Issue affects only 1.7 machine type as ACPI tables supported by
QEMU were introduced at that time, but there wasn't PCI hotplug
for bridges till the next release (2.0).
Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization
in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info().
PS:
do not ignore error returned by object_property_add_uint32_ptr()
and abort QEMU since it's programming error which should be fixed
instead of being ignored.

This patch extends support for the `dump-guest-memory` command to the
32-bit PowerPC architecture. It relies on the assumption that a 64-bit
guest will not dump a 32-bit core file (and vice versa).
[dwg: I suspect this patch won't cover all cases, in particular a
32-bit machine type on a 64-bit qemu build. However, it does strictly
more than what we had before, so might as well apply as a starting
point]

Today, the ICS (Interrupt Controller Source) object is created and
realized by the init and realize routines of the XICS object, but some
of the parameters are only known at the machine level.
These parameters are passed from the sPAPR machine to the ICS object
in a rather convoluted way using property handlers and a class handler
of the XICS object. The number of irqs required to allocate the IRQ
state objects in the ICS realize routine is one of them.
Let's simplify the process by creating the ICS object along with the
XICS object at the machine level and link the ICS into the XICS list
of ICSs at this level also. In the sPAPR machine, there is only a
single ICS but that will change with the PowerNV machine.
Also, QOMify the creation of the objects and get rid of the
