Support add bootindex = 0 to boothash and return 0 if duplicated bootindex = 0 is set. It is nessary to add bootindex = 0 into boothash, otherwise libvirt will auto set boot dev, which will cause bootindex unchangable. Meanwhile, bootindex = 0 means disable bootindex, so it should be allowed to set duplicated bootindex = 0.
Libvirt auto-sets boot order when there is none specified. With this patch you could un-select all bootable devices and end up with an un-bootable VM. Do you really want to allow that? Also doing this will require that we hohour the explicit bootindex setting of 0 in the XML separate from when it's unpopulated. Thus this requires that the XML indeed records that an explicit value of 0 was provided by the user. Thus you must improve patch 2 to carry the appropriate tests and documentation if you want to go this route.
