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

exposes the relationships between physical
and virtual functions on SR IOV capable devices.

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.

Erroneously included the sysfs_path and parent_sysfs_path elements in
the node device xml, they were not supposed to show up there

* src/conf/node_device_conf.c: remove the output of the 2 fields

I realized that I inadvertently added a member to the def struct to
contain each device's sysfs path when there was an existing member in the
dev struct for "OS specific path to device metadat, eg sysfs"  Since the
udev backend needs to record the sysfs path while it's in the process of
creating the device, before the dev struct gets allocated, I chose to
remove the member from the dev struct.

  fields in the structure as well as parsing and serialization

If no matching device was found (cap == NULL) then no strdup() call
was made and *wwnn and *wwpn are untouched. Checking them for NULL
in this situation may result in reporting an false-positive OOM error
because *wwnn and *wwpn may be initialized to NULL by the caller.

Only check *wwnn and *wwpn for NULL if a matching device was found
(cap != NULL) and thus strdup() was called.

* src/conf/node_device_conf.c: only report an OOM error if there
  really is one

These will be used by the test driver, so move them to a shareable space.

Add virNodeDeviceParseFile, and make virNodeDeviceParseNode non-static. These
will be used by the test driver.

Add support for parsing node device XML descriptions.

This will be used by PCI passthrough related functions to
obtain the PCI device address for a given node device.
