Make CCW devices available to the node_device driver. The devices are
already seen by udev so let's implement necessary code for detecting
them properly.

Topologically, CCW devices are similar to PCI devices, e.g.:

    +- ccw_0_0_1a2b
        |
        +- scsi_host0
            |
            +- scsi_target0_0_0
                |
                +- scsi_0_0_0_0

NBD does not mandate a "filename". Gluster can have more servers. Split
them so that we can tighten the schema.

ftp/tftp/sheepdog have a mandatory filename and support only one host.
There are no additional options for them.

Make the schema more strict for HTTP disks requiring a name and
mandating exactly one source host.

ftp/tftp entries were not moved here, since http transport also will
support cookies and other options, which will be added later.

RBD driver supports specifying a snapshot image name or config file.
Create a define for RBD and move the specifics there.

Move it to the place where actually interleaving elements can be placed.

'diskSourceNetwork' schema define was rather big and it would be hard to
simplify it. Split out the host portion subelement into a separate
define.

They don't contain any elements to interleave.

This patch introduces

    <cache level='N' mode='emulate'/>
    <cache mode='passthrough'/>
    <cache mode='disable'/>

sub element of /domain/cpu. Currently only a single <cache> element is
allowed.

We are currently parsing only rx/frames/max because that's the only
value that makes sense for us.  The tun device just added support for
this one and the others are only supported by hardware devices which
we don't need to worry about as the only way we'd pass those to the
domain is using <hostdev/> or <interface type='hostdev'/>.  And in
those cases the guest can modify the settings itself.

A mediated device will be identified by a UUID (with 'model' now being
a mandatory <hostdev> attribute to represent the mediated device API) of
the user pre-created mediated device. We also need to make sure that if
user explicitly provides a guest address for a mdev device, the address
type will be matching the device API supported on that specific mediated
device and error out with an incorrect XML message.

The resulting device XML:
<devices>
  <hostdev mode='subsystem' type='mdev' model='vfio-pci'>
    <source>
      <address uuid='c2177883-f1bb-47f0-914d-32a22e3a8804'>
    </source>
  </hostdev>
</devices>

QEMU 2.9 introduces the pcie-root-port device, which is
a generic version of the existing ioh3420 device.

Make the new device available to libvirt users.

For NVDIMM devices it is optionally possible to specify the size
of internal storage for namespaces. Namespaces are a feature that
allows users to partition the NVDIMM for different uses.

Now that NVDIMM has found its way into libvirt, users might want
to fine tune some settings for each module separately. One such
setting is 'share=on|off' for the memory-backend-file object.
This setting - just like its name suggest already - enables
sharing the nvdimm module with other applications. Under the hood
it controls whether qemu mmaps() the file as MAP_PRIVATE or
MAP_SHARED.

Yet again, we have such config knob in domain XML, but it's just
an attribute to numa <cell/>. This does not give fine enough
tuning on per-memdevice basis so we need to have the attribute
for each device too.

NVDIMM is new type of memory introduced into QEMU 2.6. The idea
is that we have a Non-Volatile memory module that keeps the data
persistent across domain reboots.

At the domain XML level, we already have some representation of
'dimm' modules. Long story short, NVDIMM will utilize the
existing <memory/> element that lives under <devices/> by adding
a new attribute 'nvdimm' to the existing @model and introduce a
new <path/> element for <source/> while reusing other fields. The
resulting XML would appear as:

    <memory model='nvdimm'>
      <source>
        <path>/tmp/nvdimm</path>
      </source>
      <target>
        <size unit='KiB'>523264</size>
        <node>0</node>
      </target>
      <address type='dimm' slot='0'/>
    </memory>

So far, this is just a XML parser/formatter extension. QEMU
driver implementation is in the next commit.

With that users could access files outside /dev/shm.  That itself
isn't a security problem, but might cause some errors we want to
avoid.  So let's forbid slashes as we do with domain and volume names
and also mention that in the schema.

So far we allow to set MTU for libvirt networks. However, not all
