migration: Do not re-read the clock on pre_save in case of paused guest
The clock move makes the guest knows about the paused time between the

after migration.
So, this patch checks the runstate of guest in the pre_save handler and

x86: do not advertise die-id in query-hotpluggbale-cpus if '-smp dies' is not set
Commit
176d2cda0 (i386/cpu: Consolidate die-id validity in smp context) added
new 'die-id' topology property to CPUs and exposed it via QMP command
query-hotpluggable-cpus, which broke -device/device_add cpu-foo for existing
users that do not support die-id/dies yet. That's would be fine if it happened
to new machine type only but it also happened to old machine types,
which breaks migration from old QEMU to the new one, for example following CLI:
OLD-QEMU -M pc-i440fx-4.0 -smp 1,max_cpus=2 \
-device qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id
is not able to start with new QEMU, complaining about invalid die-id.
After discovering regression, the patch
"pc: Don't make die-id mandatory unless necessary"
makes die-id optional so old CLI would work.
However it's not enough as new QEMU still exposes die-id via query-hotpluggbale-cpus
QMP command, so the users that started old machine type on new QEMU, using all
properties (including die-id) received from QMP command (as required), won't be
able to start old QEMU using the same properties since it doesn't support die-id.
Fix it by hiding die-id in query-hotpluggbale-cpus for all machine types in case
'-smp dies' is not provided on CLI or -smp dies = 1', in which case smp_dies == 1
and APIC ID is calculated in default way (as it was before DIE support) so we won't
need compat code as in both cases the topology provided to guest via CPUID is the same.

hostmem-file: fix pmem file size check
Commit
314aec4a6e06844937f1677f6cba21981005f389 ("hostmem-file: reject
invalid pmem file sizes") added a file size check that verifies the
hostmem object's size parameter against the actual devdax pmem file.
This is useful because getting the size wrong results in confusing
errors inside the guest.
However, the code doesn't work properly for files where struct
stat::st_size is zero. Hostmem-file's ->alloc() function returns early
without setting an Error, causing the following assertion failure:
qemu/memory.c:2215: memory_region_get_ram_ptr: Assertion `mr->ram_block' failed.
This patch handles the case where qemu_get_pmem_size() returns 0 but
there is no error.

qapi: report the default CPU type for each machine
When user doesn't request any explicit CPU model with libvirt or QEMU,
a machine type specific CPU model is picked. Currently there is no way
to determine what this QEMU built-in default is, so libvirt cannot
report this back to the user in the XML config.
This extends the "query-machines" QMP command so that it reports the
default CPU model typename for each machine.

pc: Don't make die-id mandatory unless necessary
We have this issue reported when using libvirt to hotplug CPUs:
https://bugzilla.redhat.com/show_bug.cgi?id=
1741451
Basically, libvirt is not copying die-id from
query-hotpluggable-cpus, but die-id is now mandatory.
We could blame libvirt and say it is not following the documented
interface, because we have this buried in the QAPI schema
documentation:
> Note: currently there are 5 properties that could be present
> but management should be prepared to pass through other
> properties with device_add command to allow for future
> interface extension. This also requires the filed names to be kept in
> sync with the properties passed to -device/device_add.
But I don't think this would be reasonable from us. We can just
make QEMU more flexible and let die-id to be omitted when there's
no ambiguity. This will allow us to keep compatibility with
existing libvirt versions.
Test case included to ensure we don't break this again.
