qdev hotplug: infrastructure and monitor commands.
Adds device_add and device_del commands. device_add accepts accepts
the same syntax like the -device command line switch. device_del
expects a device id. So you should tag your devices with ids if you
want to remove them later on, like this:
device_add pci-ohci,id=ohci
device_del ohci
Unplugging via pci_del or usb_del works too.
