Re: [libvirt] [PATCH] nwfilter: fix crash during filter define when lxc driver failed startup

The meat of this patch is just moving the calls to virNWFilterRegisterCallbackDriver from each hypervisor's "register" function into its "initialize" function. The rest is just code movement to allow that, and a new virNWFilterUnRegisterCallbackDriver function to undo what the register function does. The long explanation:
