All these cleanup/error labels were reduced to having just "return
ret" by a previous patch, so get rid of them and return directly.
This patch coincidentally fixes a bug in
networkFindUnusedBridgeName(), where we would log an error yet still
return success if we failed to find a single unused "virbrNNN" name
after checking all values of "N" from 0 - 256. Said bug was introduced
when that function was originally written, in commit a28d3e485f

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.

Commit <f650e86703847af544762d02f79c70131ff7fbab> added check for
openpty function from util library using AC_CHECK_LIB(). However, that
macro doesn't define OPENPTY_LIBS, it only defines WITH_LIBUTIL and
prepends -lutil into LIBS for the whole project.

This check was introduced by commit
<96a02703daad4dc6663165adbc0feade9900cebd> to guard calling
sanlock_inq_lockspace() function but it used SANLK_INQ_WAIT as a
parameter which was introduced later. This was eventually fixed by
commit <238dba0f9c925359cb3b8beddd8c8ae739cb4e06>.
We can safely replace check for sanlock_inq_lockspace as that function
was introduced in sanlock-1.9. The oldest used version, sanlock-2.2,
is by Ubuntu 16.04.
