This new element is there to represent PCI-Express capabilities
of a PCI devices, like link speed, number of lanes, etc.

While exposing the info under <interface/> in previous patch works, it
may work only in cases where interface is configured on the host.
However, orchestrating application may want to know the link state and
speed even in that case. That's why we ought to expose this in nodedev
XML too:

virsh # nodedev-dumpxml net_eth0_f0_de_f1_2b_1b_f3
<device>
  <name>net_eth0_f0_de_f1_2b_1b_f3</name>
  <path>/sys/devices/pci0000:00/0000:00:19.0/net/eth0</path>
  <parent>pci_0000_00_19_0</parent>
  <capability type='net'>
    <interface>eth0</interface>
    <address>f0:de:f1:2b:1b:f3</address>
    <link speed='1000' state='up'/>
    <capability type='80203'/>
  </capability>
</device>

A PCI device can be associated with a specific NUMA node. Later, when
a guest is pinned to one NUMA node the PCI device can be assigned on
different NUMA node. This makes DMA transfers travel across nodes and
thus results in suboptimal performance. We should expose the NUMA node
locality for PCI devices so management applications can make better
decisions.

Commit id 'c4a4603d' added an output <path> to the nodedev xml, but
did not update the schema.

This resulted in the failure of the 'virt-xml-validate' on a file
generated by 'virsh nodedev-dumpxml pci_0000_00_00_0' (for example).

This was found/seen by running autotest on my host.

This includes adding it to the nodedev parser and formatter, docs, and
test.

An example of the new iommuGroup element that is a part of the output
from "virsh nodedev-dumpxml" (virNodeDeviceGetXMLDesc()):

  <device>
    <name>pci_0000_02_00_1</name>
    <capability type='pci'>
    ...
      <iommuGroup number='12'>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/>
      </iommuGroup>
    </capability>
  </device>

This enrichs HBA's xml by dumping the number of max vports and
vports in use. Format is like:

  <capability type='vport_ops'>
    <max_vports>164</max_vports>
    <vports>5</vports>
  </capability>

* docs/formatnode.html.in: (Document the new XML)
* docs/schemas/nodedev.rng: (Add the schema)
* src/conf/node_device_conf.h: (New member for data.scsi_host)
* src/node_device/node_device_linux_sysfs.c: (Collect the value of
  max_vports and vports)

Just add the head line to let the editor know it's XML document.

* docs/formatdomain.html.in: Add document.
* docs/schemas/nodedev.rng: Move definition of "wwn" to ...
* docs/schemas/basictypes.rng: ...Here
* docs/schemas/domaincommon.rng: Add schema for disk <wwn>

It should be [] instead of ().

capability.rng: Guest features can be in any order.
nodedev.rng: Added <driver> element, <capability> phys_function and
virt_functions for PCI devices.
storagepool.rng: Owner or group ID can be -1.

schema tests: New capabilities and nodedev files; changed owner and
group to -1 in pool-dir.xml.
storage_conf: Print uid_t and gid_t as signed to storage pool XML.

The schema files contained duplicate data types that can be shared from
the basictypes.rng file.

This patch is to expose the fabric_name of fc_host class, which
might be useful for users who wants to known which fabric the
(v)HBA connects to.

The patch also adds the missed capabilities' XML schema of scsi_host,
(of course, with fabric_wwn added), and update the documents
(docs/formatnode.html.in)

* docs/schemas/capability.rng: Likewise.
* docs/schemas/network.rng: Likewise.
* docs/schemas/nodedev.rng: Likewise.
* docs/schemas/storagepool.rng: Likewise.
* docs/schemas/storagevol.rng: Likewise.
Use these commands:
t=$'\t'
git ls-files | grep '\.rng$' | xargs grep -lE "^ *$t" \
  | xargs perl -MText::Tabs -ni -le \
    '$m=/^( *\t[ \t]*)(.*)/; print $m ? expand($1) . $2 : $_'

Provides the CDROM label for current media. Only implemented for the
udev backend.

* docs/schemas/*.rng: the comments were wrong
* src/qemu_conf.c: typo in an error message
