Effectively move code from nwfilter_driver.c into virnwfiltereobj to
count the number of devices, to return a list of names, and to return
an array of filters.
FWIW: This is part of the common driver objects code I've been working
through. I figured I will post each driver separately rather than one
larger series.

New subject: [libvirt] [PATCH 1/3] nwfilter: Introduce virNWFilterObjNumOfNWFilters
Mostly code motion from nwfilter_driver to virnwfilterobj with one caveat
to add the virNWFilterObjListFilter typedef and pass it as an 'aclfilter'
argument to allow for future possible test driver adjustments to count
the number of filters (similar to how node device has done this).

New subject: [libvirt] [PATCH 2/3] nwfilter: Introduce virNWFilterObjGetNames
Mostly code motion to move nwfilterConnectListNWFilters into nwfilterobj.c
and rename to virNWFilterObjGetNames.
Also includes a couple of variable name adjustments to keep code consistent
with other drivers.
