This QEMU_VM_COMMAND sub-command and its switchover_start SaveVMHandler is
used to mark the switchover point in main migration stream.
It can be used to inform the destination that all pre-switchover main
migration stream data has been sent/received so it can start to process
post-switchover data that it might have received via other migration
channels like the multifd ones.
Add also the relevant MigrationState bit stream compatibility property and
its hw_compat entry.

Migration code wants to manage device data sending threads in one place.
QEMU has an existing thread pool implementation, however it is limited
to queuing AIO operations only and essentially has a 1:1 mapping between
the current AioContext and the AIO ThreadPool in use.
Implement generic (non-AIO) ThreadPool by essentially wrapping Glib's
GThreadPool.
This brings a few new operations on a pool:
* thread_pool_wait() operation waits until all the submitted work requests
have finished.
* thread_pool_set_max_threads() explicitly sets the maximum thread count
in the pool.
* thread_pool_adjust_max_threads_to_work() adjusts the maximum thread count
in the pool to equal the number of still waiting in queue or unfinished work.

It's possible for {load,save}_cleanup SaveVMHandlers to get called without
the corresponding {load,save}_setup handler being called first.
One such example is if {load,save}_setup handler of a proceeding device
returns error.
In this case the migration core cleanup code will call all corresponding
cleanup handlers, even for these devices which haven't had its setup
handler called.
Since this behavior can generate some surprises let's clearly document it
in these SaveVMHandlers description.

The memory and IO BARs for devices are only accessible in the D0 power
state. In other power states the PCI spec defines that the device
responds to TLPs and messages with an Unsupported Request response.
To approximate this behavior, consider the BARs as unmapped when the
device is not in the D0 power state. This makes the BARs inaccessible
and has the additional bonus for vfio-pci that we don't attempt to DMA
map BARs for devices in a non-D0 power state.
To support this, an interface is added for devices to register the PM
capability, which allows central tracking to enforce valid transitions
and unmap BARs in non-D0 states.
NB. We currently have device models (eepro100 and pcie_pci_bridge)
that register a PM capability but do not set wmask to enable writes to
the power state field. In order to maintain migration compatibility,
this new helper does not manage the wmask to enable guest writes to
initiate a power state change. The contents and write access of the
PM capability are still managed by the caller.

This patch introduces temperature event notification support to the UFS

temperature-related events, including high and low temperature
notifications, in compliance with the UFS specification.
With this feature, UFS drivers can now handle temperature exception events
during testing and development within the emulated environment.
This enhances validation and debugging capabilities for thermal event
handling in UFS implementations.

Apple has its own virtio-blk PCI device ID where it deviates from the
official virtio-pci spec slightly: It puts a new "apple type"
field at a static offset in config space and introduces a new barrier
command.
This patch first creates a mechanism for virtio-blk downstream classes to
handle unknown commands. It then creates such a downstream class and a new
vmapple-virtio-blk-pci class which support the additional apple type config
identifier as well as the barrier command.
The 'aux' or 'root' device type are selected using the 'variant' property.

This file defines the register interface of the uefi-vars device.
It's only a handful of registers: magic value, command and status
registers, location and size of the communication buffer.

edk2 looks for the etc/hardware-info fw_cfg file to discover hardware
which can not easily be found in other ways. Entries consist of a
header with hardware type and entry size (HARDWARE_INFO_HEADER),
followed by the actual hardware description (which is type specific).
The file can have multiple entries.
This patch adds the infrastructure to add entries to the file and an
entry struct for simple devices (HARDWARE_INFO_SIMPLE_DEVICE) which have
an mmio address only.

The nvme_aio_err() does not handle Verify, Compare, Copy and other misc
commands and defaults to setting the error status code to Internal
Device Error. For some of these commands, we know better, so set it
explicitly.
For the commands using the nvme_misc_cb() callback (Copy, Flush, ...),
if no status code has explicitly been set by the lower handlers, default
to Internal Device Error as previously.

The controller incorrectly allows a zoned namespace to be attached even
if CS.CSS is configured to only support the NVM command set for I/O
queues.
Rework handling of namespace command sets in general by attaching
supported namespaces when the controller is started instead of, like
now, statically when realized.

On the real device, the PCIe root bus is only connected to a PCIe bridge and
does not allow for direct attachment of devices. Doing so in QEMU results in no
PCI devices being detected by Linux. Instead, PCI devices should plug into the
secondary PCIe bus spawned by the internal PCIe bridge.
Unfortunately, QEMU defaults to plugging devices into the PCIe root bus. To work
around this, every PCI device created on the command line needs an extra
`bus=dw-pcie` option which is error prone. Fix that by marking the PCIe root bus
as full which makes QEMU decend into the child PCIe bus.
