capitalized or full lower case, never Scsi.

Completely mechanical changes, but there were a lot of lines so I made
it a separate patch.

This fixes a possible double free. In virNetworkAssignDef() if
virBitmapNew() fails, then virNetworkObjFree(network) is called.
However, with network->def pointing to actual @def. So if caller
frees @def again, ...

Moreover, this fixes one possible memory leak too. In
virInterfaceAssignDef() if appending to the list of interfaces
fails, we ought to call virInterfaceObjFree() instead of bare
VIR_FREE().

Although, in order to do that some array size variables needs
to be turned into size_t rather than int.

Currently, during XML parsing, when a call to a FromString() function to
get an enum value fails, the error which is reported is either
VIR_ERR_CONFIG_UNSUPPORTED, VIR_ERR_INTERNAL_ERROR or VIR_ERR_XML_ERROR.

This commit makes such conversion failures consistently return
VIR_ERR_CONFIG_UNSUPPORTED.

'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can).  But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).

Fix up remaining offenders in src/conf, and their fallout.

PASS: nodedevxml2xmltest

The first error was resolved by adding a missing VIR_FREE(numberStr); in
the new function virNodeDevCapPciDevIommuGroupParseXML().

The second error was a bit more opaque as the error was a result of copying
the free methodolgy of the existing code in virNodeDevCapsDefFree(). The code
would free each of the entries in the array, but not the memory for the
array itself.  Added the necessary VIR_FREE(data->pci_dev.iommuGroupDevices)
and while at it added the missing VIR_FREE(data->pci_dev.virtual_functions)
although there wasn't a test that tripped across it (thus it's been lurking
since commit id 'a010165d').

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>

Since scsi generic device doesn't have DEVTYPE property set, the
only way to know if it's a  scsi generic device or not is to read
the "SUBSYSTEM" property.

The XML of the scsi generic device will be like:

<device>
  <name>scsi_generic_sg0</name>
  <path>/sys/devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0/scsi_generic/sg0</path>
  <parent>scsi_0_0_0_0</parent>
  <capability type='scsi_generic'>
    <char>/dev/sg0</char>
  </capability>
</device>

The name format is constructed by libvirt, it's not that clear to
get what the device's sysfs path should be. This exposes the device's
sysfs path by a new tag <path>.

Since the sysfspath is filled during enumerating the devices by
either udev or HAL. It's an output-only tag.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

Detected by a simple Shell script:

for i in $(git ls-files -- '*.[ch]'); do
    awk 'BEGIN {
        fail=0
    }
    /# *include.*\.h/{
        match($0, /["<][^">]*[">]/)
        arr[substr($0, RSTART+1, RLENGTH-2)]++
    }
    END {
        for (key in arr) {
            if (arr[key] > 1) {
                fail=1
                printf("%d %s\n", arr[key], key)
            }
        }
        if (fail == 1)
            exit 1
    }' $i

    if test $? != 0; then
        echo "Duplicate header(s) in $i"
    fi
done;

A later patch will add the syntax-check to avoid duplicate
headers.

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)

VIR_CONNECT_LIST_NODE_DEVICES_CAP_FC_HOST to filter the FC HBA,
and VIR_CONNECT_LIST_NODE_DEVICES_CAP_VPORTS to filter the FC HBA
which supports vport.

Guess it was created for the fc_host and vports_ops capabilities
purpose, but there is enum virNodeDevScsiHostCapFlags for them,
and enum virNodeDevHBACapType is unused, and actually both
VIR_ENUM_DECL and VIR_ENUM_IMPL use the wrong enum name
"virNodeDevHBACap".

Rename all the pciDeviceXXX and pciXXXDevice APIs to have a
fixed virPCIDevice name prefix

The auto-generated WWN comply with the new addressing schema of WWN:

<quote>
the first nibble is either hex 5 or 6 followed by a 3-byte vendor
identifier and 36 bits for a vendor-specified serial number.
</quote>

We choose hex 5 for the first nibble. And for the 3-bytes vendor ID,
we uses the OUI according to underlying hypervisor type, (invoking
virConnectGetType to get the virt type). e.g. If virConnectGetType
returns "QEMU", we use Qumranet's OUI (00:1A:4A), if returns
ESX|VMWARE, we use VMWARE's OUI (00:05:69). Currently it only
supports qemu|xen|libxl|xenapi|hyperv|esx|vmware drivers. The last
36 bits are auto-generated.

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)

When user pass wrong root element, it is not 'internal error' and
we can give him hint what we are expecting.

Commit 498d7833 cleans up some of virtual file names for parsing strings
in memory. This patch cleans up (hopefuly) the rest forgotten by the
first patch.

This patch also changes all of the previously modified "filenames" to
valid URI's replacing spaces for underscores.

Changes to v1:
- Replace all spaces for underscores, so that the strings form valid
  URI's
- Replace spaces in places changed by commit 498d7833

This patch moves some of the sriov related pci code from node_device driver
to src/util/pci.[ch]. Some functions had to go thru name and argument list
change to accommodate the move.
