Previous patch made it possible for the QEMU driver to check if
a given PCI hostdev is unassigned, by checking if dev->info->type is
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_UNASSIGNED, meaning that this device
shouldn't be part of the actual guest launch.

This patch introduces a new PCI hostdev address type called
'unassigned'. This new type gives users the option to add
PCI hostdevs to the domain XML in an 'unassigned' state, meaning
that the device exists in the domain, is managed by Libvirt
like any regular PCI hostdev, but the guest does not have
access to it.

This adds extra options for managing PCI device binding
inside Libvirt, for example, making all the managed PCI hostdevs
declared in the domain XML to be detached from the host and bind
to the chosen driver and, at the same time, allowing just a
subset of these devices to be usable by the guest.

Next patch will use this new address type in the QEMU driver to
avoid adding unassigned devices to the QEMU launch command line.

If the host OS doesn't have NUMA present, we fallback to
populating fake NUMA info and the code thus assumes only a
single NUMA node.

Unfortunately we also fallback to fake NUMA if numactl-devel
was not present, and in this case we can still have multiple
NUMA nodes. In this case we create all CPUs, but only the
CPUs in the first node have any data filled in, resulting in
capabilities like:

The current 'for' loop with 5 consecutive 'ifs' inside
qemuBuildHostdevCommandLine can be a bit smarter:

- all 5 'ifs' fails if hostdev->mode is not equal to
VIR_DOMAIN_HOSTDEV_MODE_SUBSYS. This check can be moved to the
start of the loop, failing to the next element immediately
in case it fails;

- all 5 'ifs' checks for a specific subsys->type to build the proper
command line argument (virHostdevIsSCSIDevice and virHostdevIsMdevDevice
do that but within a helper). Problem is that the code will keep
checking for matches even if one was already found, and there is
no way a hostdev will fit more than one 'if' (i.e. a hostdev can't
have 2+ different types). This means that a SUBSYS_TYPE_USB will
create its command line argument in the first 'if', then all other
conditionals will surely fail but will end up being checked anyway.

All of this can be avoided by moving the hostdev->mode comparing
to the start of the loop and using a switch statement with
subsys->type to execute the proper code for a given hostdev
type.
