The function nwfilterBindingCreateXML() is failing to compile due to a
conditional branch which leads to an undefined 'obj' variable. So 'obj'
must have an initial value to avoid compilation errors. See the problem:

Starting with QEMU 2.9, encryption convert processing requires
a multi-step process in order to generate an encrypted image from
some non encrypted raw image.
Processing requires to first create an encrypted image using the
sizing parameters from the input source and second to use the
--image-opts, -n, and --target-image-opts options along with inline
driver options to describe the input and output files, generating
two commands such as:
$ qemu-img create -f luks \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
-o key-secret=demo.img_encrypt0 \
demo.img 500K
Formatting 'demo.img', fmt=luks size=512000 key-secret=demo.img_encrypt0
$ qemu-img convert --image-opts -n --target-image-opts \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
driver=raw,file.filename=sparse.img \
driver=luks,file.filename=demo.img,key-secret=demo.img_encrypt0
$
This patch handles the convert processing by running the processing
in a do..while loop essentially reusing the existing create logic and
arguments to create the target vol from the inputvol and then converting
the inputvol using new arguments.
This then allows the following virsh command to work properly:
virsh vol-create-from default encrypt1-luks.xml data.img --inputpool default
where encrypt1-luks.xml would provided the path and secret for
the new image, while data.img would be the source image.

This allows the virsh commands nwfilter-binding-create and
nwfilter-binding-delete to be used.
Note using these commands lets you delete filters that were
previously created automatically by the virt drivers, or add
filters for VM nics that were not there before. Generally it
is expected these new APIs will only be used by virt drivers.
It is the admin's responsibility to not shoot themselves 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.

Currently the nwfilter driver does not keep any record of what filter
bindings it has active. This means that when it needs to recreate
filters, it has to rely on triggering callbacks provided by the virt
drivers. This introduces a hash table recording the virNWFilterBinding
objects so the driver has a record of all active filters.
