Michal Privoznik 228a27f59b security: Reintroduce virSecurityManager{Set,Restore}SavedStateLabel
These APIs were removed/renamed in v6.5.0-rc1~142 and v6.5.0-rc1~141
because they deemed unused. And if it wasn't for the RFE [1] things
would stay that way.

The RFE asks for us to not change DAC ownership on the file a domain is
restoring from. We have been doing that for ages (if not forever),
nevertheless it's annoying because if the restore file is on an NFS
remembering owner won't help - NFS doesn't support XATTRs yet. But more
importantly, there is no need for us to chown() the file because when
restoring the domain the file is opened and the FD is then passed to
QEMU. Therefore, we really need only to set SELinux and AppArmor.

This reverts bd22eec903.
This partially reverts 4ccbd207f2.

The difference to the original code is that secdrivers are now
not required to provide dummy implementation to avoid
virReportUnsupportedError(). The callback is run if it exists, if
it doesn't zero is returned without any error.

==============================
Libvirt API for virtualization
==============================

Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.

Further information about the libvirt project can be found on the
website:
