[libvirt] Resubmission #2: [PATCH 1/3] sVirt AppArmor security driver

[PATCH 1] patch_1_reenable-nonfile-labels.patch (Updated based on prior feedback): When James Morris originally submitted his sVirt patches (as seen in libvirt 0.6.1), he did not require on disk labelling for virSecurityDomainRestoreImageLabel. A later commit[2] changed this behavior to assume on disk labelling, which halts implementations for path-based MAC systems such as AppArmor and TOMOYO where vm->def->seclabel is required to obtain the label. This patch simply adds the 'virDomainObjPtr vm' argument back to *RestoreImageLabel.
