[libvirt] [PATCH 16/22] API: implement RPC calls for virNodeDeviceReAttachFlags



This requires a custom function for remoteNodeDeviceReAttachFlags,
because it is named *NodeDevice, but it goes through the hypervisor
driver rather than nodedevice driver, and so it uses privateData
instead of nodeDevicePrivateData. (It has to go through the hypervisor
driver, because that is the driver that knows about the backend drivers
that will perform the pci device assignment).
