Pass-through devices of a VM are not necessarily in the same group and
all groups/address_spaces need to be scanned when the machine is
reset. Commit f16f39c3fc97 ("Implement PCI hot reset") introduced a VM
reset handler for this purpose. Move it under device.c

Also reintroduce the comment which explained the context and was lost
along the way.

vfio: Introduce new files for VFIORegion definitions and declarations

Gather all VFIORegion related declarations and definitions into their
own files to reduce exposure of VFIO internals in "hw/vfio/vfio-common.h".
They were introduced for 'vfio-platform' support in commits
db0da029a185 ("vfio: Generalize region support") and a664477db8da
("hw/vfio/pci: Introduce VFIORegion").

To be noted that the 'vfio-platform' devices have been deprecated and
will be removed in QEMU 10.2. Until then, make the declarations
available externally for 'sysbus-fdt.c'.

vfio/migration: Multifd device state transfer support - send side

Implement the multifd device state transfer via additional per-device
thread inside save_live_complete_precopy_thread handler.

Switch between doing the data transfer in the new handler and doing it
in the old save_state handler depending if VFIO multifd transfer is enabled
or not.

vfio/migration: Multifd device state transfer support - load thread

Add a thread which loads the VFIO device state buffers that were received
via multifd.

Each VFIO device that has multifd device state transfer enabled has one
such thread, which is created using migration core API
qemu_loadvm_start_load_thread().

Since it's important to finish loading device state transferred via the
main migration channel (via save_live_iterate SaveVMHandler) before
starting loading the data asynchronously transferred via multifd the thread
doing the actual loading of the multifd transferred data is only started
from switchover_start SaveVMHandler.

switchover_start handler is called when MIG_CMD_SWITCHOVER_START
sub-command of QEMU_VM_COMMAND is received via the main migration channel.

This sub-command is only sent after all save_live_iterate data have already
been posted so it is safe to commence loading of the multifd-transferred
device state upon receiving it - loading of save_live_iterate data happens
synchronously in the main migration thread (much like the processing of
MIG_CMD_SWITCHOVER_START) so by the time MIG_CMD_SWITCHOVER_START is
processed all the proceeding data must have already been loaded.

vfio/migration: Multifd device state transfer support - received buffers queuing

The multifd received data needs to be reassembled since device state
packets sent via different multifd channels can arrive out-of-order.

Therefore, each VFIO device state packet carries a header indicating its
position in the stream.
The raw device state data is saved into a VFIOStateBuffer for later
in-order loading into the device.

The last such VFIO device state packet should have
VFIO_DEVICE_STATE_CONFIG_STATE flag set and carry the device config state.

And rename existing load_device_config_state trace event to

This way both the start and end points of particular device config
loading operation (a long, BQL-serialized operation) are known.
