As Coverity points out (CID 1508621) the calculation to increment i in
the fill fallback loop is ineffective as it is overwritten in next
statement. This was left there by mistake from a previous version but
is not needed in the current approach so remove the superfluous
increment statement.

No need to use an intermediate 'dma-offset' property in the
chipset object. Alias the property, so when the machine (here
r2d-plus) sets the value on the chipset, it is propagated to
the OHCI object.
Note we can rename the chipset 'base' property as 'dma-offset'
since the object is a non-user-creatable sysbus type.

PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the
header don't actually need them. Similar structs live in their own
headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in
pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h,
PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and
PCIESlot in pcie_port.h.
Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with
the code that needs them. Adjust include directives.
This also enables the next commit.

[Conflicts in hw/misc/empty_slot.c and hw/sparc/leon3.c resolved]
sm501_init() and ati_vga_realize() create an "i2c-ddc" device, but
neglect to realize it. Affects machines sam460ex, shix, r2d, and
fulong2e.
In theory, a device becomes real only on realize. In practice, the
transition from unreal to real is a fuzzy one. The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize). Depending on
what exactly is done where, a device can work even when we neglect
to realize it.
This one appears to work. Nevertheless, it's a clear misuse of the
interface. Even when it works today (more or less by chance), it can
break tomorrow.
Fix by realizing it right away. Visible in "info qom-tree"; here's
the change for sam460ex:
/machine (sam460ex-machine)
[...]
/unattached (container)

which expands to:
((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name),

This assertion can only fail when @obj points to something other
than its stated type, i.e. when we're in undefined behavior country.

pointer is of DeviceState type.

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.
