  mtree: remove write-only field
  memory: Use canonical path component as the name
  memory: Use memory_region_name for name access
  memory: constify memory_region_name
  exec: Abstract away ref to memory region names
  loader: Abstract away ref to memory region names
  tpm_tis: remove instance_finalize callback
  memory: remove memory_region_destroy
  memory: convert memory_region_destroy to object_unparent
  ioport: split deletion and destruction
  nic: do not destroy memory regions in cleanup functions
  vga: do not dynamically allocate chain4_alias
  sysbus: remove unused function sysbus_del_io
  qom: object: move unparenting to the child property's release callback
  qom: object: delete properties before calling instance_finalize
  virtio-scsi: implement parse_cdb
  scsi-block, scsi-generic: implement parse_cdb
  scsi-block: extract scsi_block_is_passthrough
