Implement PCI passthrough for xenapi driver.
We will add the support for updating the status of the host by adding a plugin which uses the "pciback" driver in dom0 to list the PCI devices we can pass through.
We will add the mechanism to attach a pci device to a VM when booting. The attachement of PCI devices will be one of the steps in creating the VM. We won't support hot-plugging of PCI devices.
To list the devices, we will need an additional xenapi plugin, as xenapi does not allow us to list all PCI devices yet, it only lets us attach them.
This will simply piggy-back the support that the libvirt driver currently has, so we don't expect and changes above the driver level as part of this blueprint, and we don't expect any new configuration settings.

Add the support for updating the status of the host. We added a function into the workarounds plugin to get information about PCI devices that are passed on the pciback.hide dom0 command line. Then we check if devices that are hidden from dom0 are availab
