  pci/shpc: convert SHPC hotplug to use hotplug-handler API
  acpi/piix4pm: convert ACPI PCI hotplug to use hotplug-handler API
  qdev:pci: refactor PCIDevice to use generic "hotpluggable" property
  hw/acpi: move typeinfo to the file end
  qdev: add "hotpluggable" property to Device
  qdev: add to BusState "hotplug-handler" link
  define hotplug interface
  loader: document that errno is set
  pc.c: better error message on initrd sizing failure
