Changes since v4:

Pushed former patch 1/4 since it was ACK'd...

 - Patch 2:
   * Return NULL on error in virNWFilterObjListFindInstantiateFilter
     instead of the somewhat obfuscated @obj which would be NULL as a
     result of the virNWFilterObjEndAPI

   * Use virNWFilterObjDemoteFromWrite prior to return obj when the
     path was returning a write locked object.

 - Patch 3:
   * Reword the comment prior to virNWFilterObjListFindByNameLocked
     in order to better explain what's happening

   * Ensure the write lock occurs while the nwfilters lock is held.

   * Fix the virNWFilterCountData setup

   * Fix the formatting for the @def in virNWFilterObjListExportCallback
     (there was an extra space)

 - Patch 4:
   * No change, still needs the official ACK/R-b though

NB: Testing done...

 * Ran/passed the nwfilter concurrency test w/ the changes

 * Ran/passed the Avocado nwfilter_update_lock, nwfilter_update_vm_running,
   and virsh.nwfilter_undefine.error_test.acl_test tests - these were the
   ones with the most nwfilter "interaction" that would cause issues at
   various points in time during installation.

John Ferlan (3):
  nwfilter: Convert _virNWFilterObj to use virObjectRWLockable
  nwfilter: Convert _virNWFilterObjList to use virObjectRWLockable
  nwfilter: Remove need for nwfilterDriverLock in some API's
