[PATCH 0/2] vmstate-static-checker: Fix VMS_ARRAY comparisons

[Peter Xu <peterx@redhat.com>]

I'm doing some machine type checks to make sure nothing breaks for
7.2<->8.0.  Along the way I found one false negative report on e1000e using
the static checker, turns out to be an issue in the checker itself.

The problem is the checker doesn't take VMS_ARRAY into account when
comparing with UNUSED, hence the total size is wrongly calculated.

Fix that first in qemu by start dumping size of array as "num", then teach
the checker for that.

NOTE: the patchset will change both behaviors for either -dump-vmstate on
QEMU or the checker, however both patches will be compatible even with old
QEMU dumps or even old vmstate-checker script.  That's not extremely
important, IMHO, but still worth mentioning.

Thanks,

  migration/vmstate-dump: Dump array size too as "num"
  vmstate-static-checker: Recognize "num" field
