[libvirt] [PATCH 00/12] Have 'buildVol' callers to clean up after themselves

NOTE: Although one may consider this a v2 of : http://www.redhat.com/archives/libvir-list/2015-October/msg00196.html It's more tackling the same problem a different way... Rather than pass a 'created' boolean around, this series investigated each of the 'createVol' and 'buildVol' paths in order to make more conscious decisions related to whether or not a volume was created and to handle failures after creation by deleting the volume/file. The end result is that all the 'buildVol' backends will now delete the volume they created on error paths leaving the storage driver to only need to remove the volume from the pool. As such this series will also revert a prior patch in this area.
