Verify that the checkpoint requested by an incremental backup exists.
Unfortunately validating whether the checkpoint configuration actually
matches the disk may not be reasonably feasible as the disk may have

The remember owner feature uses XATTRs to store original
seclabels. But that means we don't want a regular user to be able
to change what we stored and thus trick us into setting different
seclabel. Therefore, we use namespaces that are reserved to
CAP_SYS_ADMIN only. Such namespaces exist on Linux and FreeBSD.
That also means, that the whole feature is enabled only for
qemu:///system. Now, while the secdriver code is capable of
dealing with XATTRs being unsupported (it has to, not all
filesystems support them) if the feature is enabled users will
get an harmless error message in the logs and the feature
disables itself.
Since we have virSecurityXATTRNamespaceDefined() we can use it to
make a wiser decision on the default state of the feature.

that the owner was not restored on. But so far only DAC driver is
checked. Implement missing pieces and enable SELinux testing too.
This is done by mocking some libselinux APIs and following the
same logic used for DAC - everything is implemented in memory,
there is new hash table introduced that holds SELinux labels for
paths that were setfilecon_raw()-ed and in the end the hash table
is checked for entries that don't have the default SELinux label
(i.e. were not restored).
