John Ferlan 2b13361bc7 nodedev: Add the ability to create vHBA by parent wwnn/wwpn or fabric_wwn
https://bugzilla.redhat.com/show_bug.cgi?id=1349696

When creating a vHBA, the process is to feed XML to nodeDeviceCreateXML
that lists the <parent> scsi_hostX to use to create the vHBA. However,
between reboots, it's possible that the <parent> changes its scsi_hostX
to scsi_hostY and saved XML to perform the creation will either fail or
create a vHBA using the wrong parent.

So add the ability to provide "wwnn" and "wwpn" or "fabric_wwn" to
the <parent> instead of a name of the scsi_hostN that is the parent.
The allowed XML will thus be:

  <parent>scsi_host3</parent>  (current)

or

  <parent wwnn='$WWNN' wwpn='$WWPN'/>

or

  <parent fabric_wwn='$WWNN'/>

Using the wwnn/wwpn or fabric_wwn ensures the same 'scsi_hostN' is
selected between hardware reconfigs or host reboots. The fabric_wwn
Using the wwnn/wwpn pair will provide the most specific search option,
while fabric_wwn will at least ensure usage of the same SAN, but maybe
not the same scsi_hostN.

This patch will add the new fields to the nodedev.rng for input purposes
only since the input XML is essentially thrown away, no need to Format
the values since they'd already be printed as part of the scsi_host
data block.

New API virNodeDeviceGetParentHostByWWNs will take the parent "wwnn" and
"wwpn" in order to search the list of devices for matching capability
data fields wwnn and wwpn.

New API virNodeDeviceGetParentHostByFabricWWN will take the parent "fabric_wwn"
in order to search the list of devices for matching capability data field
fabric_wwn.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
