pcie: Specify 0 for ARI next function numbers

The current implementers of ARI are all SR-IOV devices. The ARI next
function number field is undefined for VF according to PCI Express Base
Specification Revision 5.0 Version 1.0 section 9.3.7.7. The PF still
requires some defined value so end the linked list formed with the field
by specifying 0 as required for any ARI implementation according to
section 7.8.7.2.

For migration, the field will keep having 1 as its value on the old
QEMU machine versions.

numa: Validate cluster and NUMA node boundary if required

For some architectures like ARM64, multiple CPUs in one cluster can be
associated with different NUMA nodes, which is irregular configuration
because we shouldn't have this in baremetal environment. The irregular
configuration causes Linux guest to misbehave, as the following warning
messages indicate.

machine: do not crash if default RAM backend name has been stolen

QEMU aborts when default RAM backend should be used (i.e. no
explicit '-machine memory-backend=' specified) but user
has created an object which 'id' equals to default RAM backend
name used by board.

$QEMU -machine pc \
-object memory-backend-ram,id=pc.ram,size=4294967296

Actual results:
QEMU 7.2.0 monitor - type 'help' for more information
(qemu) Unexpected error in object_property_try_add() at ../qom/object.c:1239:
qemu-kvm: attempt to add duplicate property 'pc.ram' to object (type 'container')
Aborted (core dumped)

Instead of abort, check for the conflicting 'id' and exit with
an error, suggesting how to remedy the issue.

hw/pci: Disable PCI_ERR_UNCOR_MASK register for machine type < 8.0

Since it's implementation on v8.0.0-rc0, having the PCI_ERR_UNCOR_MASK
set for machine types < 8.0 will cause migration to fail if the target
QEMU version is < 8.0.0 :

qemu-system-x86_64: get_pci_config_device: Bad config data: i=0x10a read: 40 device: 0 cmask: ff wmask: 0 w1cmask:0
qemu-system-x86_64: Failed to load PCIDevice:config

qemu-system-x86_64: load of migration failed: Invalid argument

The above test migrated a 7.2 machine type from QEMU master to QEMU 7.2.0,
with this cmdline:

./qemu-system-x86_64 -M pc-q35-7.2 [-incoming XXX]

In order to fix this, property x-pcie-err-unc-mask was introduced to
control when PCI_ERR_UNCOR_MASK is enabled. This property is enabled by
default, but is disabled if machine type <= 7.2.

migration: Fix potential race on postcopy_qemufile_src

postcopy_qemufile_src object should be owned by one thread, either the main
thread (e.g. when at the beginning, or at the end of migration), or by the
return path thread (when during a preempt enabled postcopy migration). If
that's not the case the access to the object might be racy.

postcopy_preempt_shutdown_file() can be potentially racy, because it's
called at the end phase of migration on the main thread, however during
which the return path thread hasn't yet been recycled; the recycle happens
in await_return_path_close_on_source() which is after this point.

It means, logically it's posslbe the main thread and the return path thread
are both operating on the same qemufile. While I don't think qemufile is
thread safe at all.

postcopy_preempt_shutdown_file() used to be needed because that's where we
send EOS to dest so that dest can safely shutdown the preempt thread.

To avoid the possible race, remove this only place that a race can happen.
Instead we figure out another way to safely close the preempt thread on
dest.

The core idea during postcopy on deciding "when to stop" is that dest will
send a postcopy SHUT message to src, telling src that all data is there.
Hence to shut the dest preempt thread maybe better to do it directly on
dest node.

This patch proposed such a way that we change postcopy_prio_thread_created
into PreemptThreadStatus, so that we kick the preempt thread on dest qemu
by a sequence of:

mis->preempt_thread_status = PREEMPT_THREAD_QUIT;
qemu_file_shutdown(mis->postcopy_qemufile_dst);

While here shutdown() is probably so far the easiest way to kick preempt
thread from a blocked qemu_get_be64(). Then it reads preempt_thread_status
to make sure it's not a network failure but a willingness to quit the
thread.

We could have avoided that extra status but just rely on migration status.
The problem is postcopy_ram_incoming_cleanup() is just called early enough
so we're still during POSTCOPY_ACTIVE no matter what.. So just make it
simple to have the status introduced.

One flag x-preempt-pre-7-2 is added to keep old pre-7.2 behaviors of
postcopy preempt.
