[libvirt] [PATCHv2 00/16] qemu block-commit support

I figured I'd better post this now, while I still iron out the remaining kinks in my SELinux handling (but I'm certainly a lot closer, now that I have libvirt actually identifying which files need the temporary SELinux labels). With this, you can now do things like 'virsh blockcommit $dom $disk --top relative_name --shallow' even when the backing chain refers to an absolute backing file name; the QMP command passed to qemu will have the correct absolute names.
