The parent device needs to report the generic stuff about the supported
mediated devices types, like device API, available instances, type name,
etc. Therefore this patch introduces a new nested capability element of
type 'mdev_types' with the resulting XML of the following format:
<device>
...
<capability type='pci'>
...
<capability type='mdev_types'>
<type id='vendor_supplied_id'>
<name>optional_vendor_supplied_codename</name>
<deviceAPI>vfio-pci</deviceAPI>
<availableInstances>NUM</availableInstances>
</type>
...
<type>
...
</type>
</capability>
</capability>
...
</device>

The reason for introducing two capabilities, one for the device itself
(cap 'mdev') and one for the parent device listing the available types
('mdev_types'), is that we should be able to do
'virsh nodedev-list --cap' not only for existing mdev devices but also
for devices that support creation of mdev devices, since one day libvirt
might be actually able to create the mdev devices in an automated way
(just like we do for NPIV/vHBA).

For both virNodeDeviceObjNumOfDevices and virNodeDeviceObjGetNames, the
check should be if the aclfilter doesn't exist or if it does exist, then
it must pass
Unify the *ListDevice API into virnodedeviceobj.c from node_device_driver
and test_driver. The only real difference between the two is that the test
driver doesn't call the aclfilter API. The name of the new API follows that
of other drivers to "GetNames".
NB: Change some variable names to match what they really are - consistency
with other drivers. Also added a clear of the input names.
This also allows virNodeDeviceObjHasCap to be static to virnodedeviceobj

Unify the NumOfDevices API into virnodedeviceobj.c from node_device_driver
and test_driver. The only real difference between the two is that the test
driver doesn't call the aclfilter API.

Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
on one line.
Move all the NodeDeviceObj API's into their own module virnodedeviceobj
from the node_device_conf
Purely code motion at this point, plus adjustments to cleanly build.
