Despite its name, this is really just a general-purpose string
manipulation function, so it should be moved to the virstring
module and renamed accordingly.
A few trivial whitespace changes are squashed in.

Now that the nwfilter driver keeps a list of bindings that it has
created, there is no need for the complex virt driver callbacks. It is
possible to simply iterate of the list of recorded filter bindings.
This means that rebuilding filters no longer has to acquire any locks on
the virDomainObj objects, as they're never touched.

Remove the unnecessary check as since commit id '46a811db07' it is
not possible to add or alter a filter using the same name, but with
a different UUID.
NB: It's not required to provide a UUID for a filter by name, but
if one is provided, then it must match the existing. If not provided,
then one is generated during ParseXML processing.

Rename the variable, recent review requested just use of @filter,
so be consistent throughout.
NB: Also change the virNWFilterPtr to be @nwfilter to not conflict
with the renamed variable.
This reverts commit b3e71a8830.
As it turns out this ends up very badly as the @def could be Free'd
even though it's owned by @obj as a result of the AssignDef.
When adding a nwfilter onto the list in
virNWFilterObjListAssignDef() this array is re-allocated to match
demand for new size. However, it is never freed leading to a
leak:

Only save the config when using a generated UUID if we were able to
create an object for the def. There could have been "other reasons"
for the assignment to fail, so saving the config could be incorrect.

Move from virnwfilterobj.h to virnwfilterobj.c.
Create the virNWFilterObjListNew() API in order to allocate.

Move the structure to virnwfilterobj.c and create necessary accessor API's
for the various fields.
Also make virNWFilterObjFree static since there's no external callers.

Rather than dereferencing obj->def->XXX or nwfilters->objs[i]->X
create local virNWFilterObjPtr and virNWFilterDefPtr variables.
Future adjustments will be privatizing the object more, so this just
prepares the code for that reality.

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).

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 NWFilterObj API's into their own module virnwfilterobj
from the nwfilter_conf
Purely code motion at this point, plus adjustments to cleanly build.
