find_missing_forward_links_from_backlinks() finds and returns missing forward-links by
searching all for all objects that link to the object in the backlink attribute.
This will be used in the next commit to restore forward links in a corrupted
forward link attribute by passing the missing backling objects to
err_recover_forward_links().

If dbcheck is not run within the tombstone lifetime, these links can
persist in the database forever. The risk of unintentional information loss
is why these links are only removed within the same partition. A
replication may be in progress which has created only one end of
the link, so we must keep that.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=12600
Samba does not maintain one way links when the target is deleted or renamed
so do not fail dbcheck because of such links, but allow them to be updated.
This matters because administrators and make test expect that normal Samba
operation do NOT cause the database to become corrupt, and any error from
dbcheck tends to trigger alarms (or test failures).
If an object pointed at by a one way link is renamed or deleted in normal
operations (such as intersiteTopologyGenerator pointing at a demoted DC),
or make test, then this could trigger.

Here we are more careful when checking links, flagging errors only
when a non-deleted forward link appears incorrect. In particular, we
trust the GUID more than we trust the name, as otherwise we can get
caught out if there is a swap of names, (the link should follow the
swap, staying on the same target GUID).

Otherwise, anything that the transaction has already done to the DB will be left in the DB
even despite the failure. For example, if a fix wrote to the DB, but then failed a post-write
check, then the fix will not be unrolled.
This is because we do not have nested transactions in TDB.

In order to do this we need to use the reveal internals control, which
breaks the comparison against extended DNs. So we compare the

Because this patch makes our code notice and fix stale one-way-links
(eg, after a rename) now, the renamedc test needs to be adjusted to

Older Samba versions could delete this. This patch tries very hard
to put back the original object, with the original GUID, so that
if another replica has the correct container, that we just merge
rather than conflict.
The existing "wrong dn" check can then put any deleted objects
under this container correctly.
