aff39be0ed hw/pci-host: Use object_initialize_child for correct reference counting
Both functions, object_initialize() and object_property_add_child() increase
the reference counter of the new object, so one of the references has to be
dropped afterwards to get the reference counting right. Otherwise the child
object might not be properly cleaned up when the parent gets destroyed.
Some functions of the pci-host devices miss to drop one of the references.
Fix it by using object_initialize_child() instead, which takes care of
calling object_initialize(), object_property_add_child() and object_unref()
in the right order.

4f91740698 hw/pci-host/xilinx-pcie: don't make "io" region be RAM
Currently we use memory_region_init_rom_nomigrate() to create
the "io" memory region to pass to pci_register_root_bus().
This is a dummy region, because this PCI controller doesn't
support accesses to PCI IO space.

There is no reason for the dummy region to be a RAM region;
it is only used as a place where PCI BARs can be mapped,
and if you could get a PCI card to do a bus master access
to the IO space it should not get acts-like-RAM behaviour.
Use a simple container memory region instead. (We do have
one PCI card model which can do bus master accesses to IO
space -- the LSI53C895A SCSI adaptor.)

This avoids the oddity of having a memory region which is
RAM but where the RAM is not migrated.

Note that the size of the region we use here has no
effect on behaviour.

d61a363d3e pci: removed the is_express field since a uniform interface was inserted
according to Eduardo Habkost's commit fd3b02c889 all PCIEs now implement
INTERFACE_PCIE_DEVICE so we don't need is_express field anymore.

Devices that implements only INTERFACE_PCIE_DEVICE (is_express == 1)
or
devices that implements only INTERFACE_CONVENTIONAL_PCI_DEVICE (is_express == 0)
where not affected by the change.

The only devices that were affected are those that are hybrid and also
had (is_express == 1) - therefor only:
  - hw/vfio/pci.c
  - hw/usb/hcd-xhci.c
  - hw/xen/xen_pt.c

For those 3 I made sure that QEMU_PCI_CAP_EXPRESS is on in instance_init()

1115ff6d26 pci: Rename root bus initialization functions for clarity
pci_bus_init(), pci_bus_new_inplace(), pci_bus_new() and pci_register_bus()
are misleadingly named.  They're not used for initializing *any* PCI bus,
but only for a root PCI bus.

Non-root buses - i.e. ones under a logical PCI to PCI bridge - are instead
created with a direct qbus_create_inplace() (see pci_bridge_initfn()).

This patch renames the functions to make it clear they're only used for
a root bus.

e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:
