The argument (if not NULL) points to the file the domain is
restoring from. On QEMU command line this used to be '-incoming
$path', but we've switched to passing FD ages ago and thus this
argument is used only in AppArmor (which loads the profile on
domain start). Anyway, the argument does not refer to stdin,
rename it to 'incomingPath' then.

Currently, when restoring from a domain the path that the domain
restores from is labelled under qemuSecuritySetAllLabel() (and after
v6.3.0-rc1~108 even outside transactions). While this grants QEMU
the access, it has a flaw, because once the domain is restored, up
and running then qemuSecurityDomainRestorePathLabel() is called,
which is not real counterpart. In case of DAC driver the
SetAllLabel() does nothing with the restore path but
RestorePathLabel() does - it chown()-s the file back and since there
is no original label remembered, the file is chown()-ed to
root:root. While the apparent solution is to have DAC driver set the
label (and thus remember the original one) in SetAllLabel(), we can
do better.
Turns out, we are opening the file ourselves (because it may live on
a root squashed NFS) and then are just passing the FD to QEMU. But
this means, that we don't have to chown() the file at all, we need
to set SELinux labels and/or add the path to AppArmor profile.
And since we want to restore labels right after QEMU is done loading
the migration stream (we don't want to wait until
qemuSecurityRestoreAllLabel()), the best way to approach this is to
have separate APIs for labelling and restoring label on the restore
file.
I will investigate whether AppArmor can use the SavedStateLabel()
API instead of passing the restore path to SetAllLabel().

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.

The difference to the original code is that secdrivers are now

virReportUnsupportedError(). The callback is run if it exists, if
it doesn't zero is returned without any error.

When locking files for metadata change, we open() them for R/W
access. The write access is needed because we want to acquire
exclusive (write) lock (to mutually exclude with other daemons
trying to modify XATTRs on the same file). Anyway, the open()
might fail if the file lives on a RO filesystem. Well, if that's
the case, ignore the error and continue with the next file on the
list. We won't change any seclabel on the file anyway - there is
nothing to remember then.
