Re: [libvirt] [PATCH 00/17] nwfilter adjustments for common object

As noted in the recently posted virObject changes: https://www.redhat.com/archives/libvir-list/2017-June/msg00070.html I believe I've found a way to handle the recursive lock situation that made it "difficult" (at best) to convert the nwfilter to the common object model. It does involve a bit of a circuitous route to "temporarily implement" the refcnt in nwfilter, but that gets removed rather quickly. Beyond that there's a bit of setup, the first few patches deal with issues seen while working through this code and then more setup for getting things to be more common with other drivers (so when they disappear a bit further into the future) into some new object it'll be obvious where/why they're there. The middle few patches deal with an insane naming scheme for a single function that seemed to keep prefixing "_" as a new function was created. So it's a bit of name change, but makes it easier to think about. The last 4 patches deal with the conversion to use a @ref, a change to a list locking hash table model, the modificiation of the recursive instantiation to use @refs rather than @locks, and finally the change to use the existing lockable object. I have run these through the various avacodo nwfilter tests that I could find, but perhaps if someone that had a more "robust configuration" and wants to be a bit adventurous and also give the patches a whirl - that would be appreciated.
