Merge remote-tracking branch 'luiz/queue/qmp' into staging

# By Laszlo Ersek
# Via Luiz Capitulino
* luiz/queue/qmp:
  dump: rebase from host-private RAMBlock offsets to guest-physical addresses
  dump: populate guest_phys_blocks
  dump: introduce GuestPhysBlockList
  dump: clamp guest-provided mapping lengths to ramblock sizes
