Support updating device's(support cdrom, disk and network) bootindex
online in virDomainUpdateDeviceFlags. The new bootindex will take effect
after guest rebooting. Enable bootindex can be set to -1, it means cancel
the device's bootindex.

To use this feature, we need to get the device's xml first and modify
the boot order in the xml, then use 'virsh update-device <domain> <xml>
--flag' to update the bootindex. Note that the flag should be --config
or --persistent if the vm is running.

  qemu: Support set bootindex to -1
  qemu: Support add bootindex = -1 to boothash
  qemu: Reserve bootindex = -1 in virDomainDeviceDefCopy

Your series doesn't pass our test suite, namely there are trailing
spaces and missing '%s' in an error message.

Make sure you run the test suite including syntax-check before your next
submission:
