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 - 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.

vfio/migration: Change trace formats from hex to decimal

Data sizes in VFIO migration trace events are printed in hex format
while in migration core trace events they are printed in decimal format.

This inconsistency makes it less readable when using both trace event
types. Hence, change the data sizes print format to decimal in VFIO
migration trace events.

hw/vfio/pci.c: Use correct type in trace_vfio_msix_early_setup()

The tracepoint trace_vfio_msix_early_setup() uses "int" for the type
of the table_bar argument, but we use this to print a uint32_t.

hw/vfio/pci.c: Use correct type in trace_vfio_msix_early_setup()

The tracepoint trace_vfio_msix_early_setup() uses "int" for the type
of the table_bar argument, but we use this to print a uint32_t.
Coverity warns that this means that we could end up treating it as a
negative number.

We only use this in printing the value in the tracepoint, so
mishandling it as a negative number would be harmless, but it's
better to use the right type in the tracepoint. Use uint64_t to
match how we print the table_offset in the vfio_msix_relo()
tracepoint.
