include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST

Now that all of the Property arrays are counted, we can remove
the terminator object from each array. Update the assertions
in device_class_set_props to match.

With struct Property being 88 bytes, this was a rather large
form of terminator. Saves 30k from qemu-system-aarch64.

Several features that landed at the last possible moment:

Passthrough HDM decoder emulation
Refactor cryptodev
RAS error emulation and injection
acpi-index support on non-hotpluggable slots
Dynamically switch to vhost shadow virtqueues at vdpa net migration

Plus a couple of bugfixes that look important to have in the release.

hw/pci: Add pcie_count_ds_port() and pcie_find_port_first() helpers

These two helpers enable host bridges to operate differently depending on
the number of downstream ports, in particular if there is only a single
port.

Useful for CXL where HDM address decoders are allowed to be implicit in
the host bridge if there is only a single root port.

pci: fix 'hotplugglable' property behavior

Currently the property may flip its state
during VM bring up or just doesn't work as
the name implies.

In particular with PCIE root port that has
'hotplug={on|off}' property, and when it's
turned off, one would expect
'hotpluggable' == false
for any devices attached to it.
Which is not the case since qbus_is_hotpluggable()
used by the property just checks for presence
of any hotplug_handler set on bus.

The problem is that name BusState::hotplug_handler
from its inception is misnomer, as it handles
not only hotplug but also in many cases coldplug
as well (i.e. generic wiring interface), and
it's fine to have hotplug_handler set on bus
while it doesn't support hotplug (ex. pcie-slot
with hotplug=off).

Another case of root port flipping 'hotpluggable'
state when ACPI PCI hotplug is enabled in this
case root port with 'hotplug=off' starts as
hotpluggable and then later on, pcihp
hotplug_handler clears hotplug_handler
explicitly after checking root port's 'hotplug'
property.

So root-port hotpluggablity check sort of works
if pcihp is enabled but is broken if pcihp is
disabled.

One way to deal with the issue is to ask
hotplug_handler if bus it controls is hotpluggable
or not. To do that add is_hotpluggable_bus()
hook to HotplugHandler interface and use it in
'hotpluggable' property + teach pcie-slot to
actually look into 'hotplug' property state
before deciding if bus is hotpluggable.

pci: acpi hotplug: rename x-native-hotplug to x-do-not-expose-native-hotplug-cap

When ACPI PCI hotplug for Q35 was introduced (6.1), it was implemented
by hiding HPC capability on PCIE slot. That however led to a number of
regressions and to fix it, it was decided to keep HPC cap exposed
in ACPI PCI hotplug case and force guest in ACPI PCI hotplug mode
by other means [1].

That reduced meaning of x-native-hotplug to a compat knob [2] for
broken 6.1 machine type.
Rename property to match its current purpose.

pcie: rename 'native-hotplug' to 'x-native-hotplug'

Mark property as experimental/internal adding 'x-' prefix.

Property was introduced in 6.1 and it should have provided
ability to turn on native PCIE hotplug on port even when
ACPI PCI hotplug is in use is user explicitly sets property
on CLI. However that never worked since slot is wired to
ACPI hotplug controller.
Another non-intended usecase: disable native hotplug on slot
when APCI based hotplug is disabled, which works but slot has
'hotplug' property for this taks.

It should be relatively safe to rename it to experimental
as no users should exist for it and given that the property
is broken we don't really want to leave it around for much
longer lest users start using it.

switch, disable hot-unplug on PCIe Root Port connected to the upstream
port as well as on the selected downstream ports.
