This patch should not alter functionality - it is just making memory
assumptions used in replmd_process_linked_attribute() clearer.
When adding/removing msg->elements we have to take care, as this will
invalidate things like the parsed-DN array or old ldb_message_element
pointers. This has always been the case (i.e. f6bc4c08b1),
however, now we need to take even more care, as the msg being modified
is re-used and split across 2 different functions.
Add more code comments to highlight this. We can also free
pdn_list/old_el to prevent them being incorrectly used after realloc.
It seems appropriate to also add a sanity-check that the tmp_ctx alloc
succeeds (which all the other memory hangs off).

Quite a bit of time was spent in dsdb_get_deleted_objects_dn()
processing during either a join (~9%) or a full-sync (~28%).
The problem is we're *always* doing the dsdb_get_deleted_objects_dn()
call for each object, regardless of whether it's actually deleted or
not. i.e. we were doing an expensive query and a lot of the time just
ignoring the query result.
If it's not a deleted object we're dealing with, we can just return
early and skip the unnecessary processing.

When a group has 10,000+ links, get_parsed_dns_trusted() can be costly
(simply the talloc calls alone are expensive). Instead of re-generating
the pdn_list for every single link attribute, we can change to only
re-generate it when we really need to.
When we add a new link, it reallocates old_el->values, and so we need to
recreate the pdn_list because all the memory pointers will have changed.
However, in the other cases, where we're simply updating the existing
link value (or ignoring the update, if it's already applied), we can
continue using the same pdn_list (rather than re-parsing it again).
This would generally only save time with a full-sync - it won't really
help with the join case (because every link processed results in a
realloc).
On a DB with 5000 users, this makes a full-sync about ~13% faster.

We should only need to lookup the msg attribute once per source object.
The old_el->values may change due to link-processing, but old_el itself
should not.
This is not aimed at improving performance, but we need to change how
old_el is used before we can change pdn_list (which is more costly
processing-wise).

At first glance, this code seemed completely unnecessary. However, it
was added (by commit f6bc4c08b1) for a valid reason: adding the
whenChanged/uSNChanged attributes to the message can cause msg->elements
to be reallocated, which means the old_el pointer (which points to
msg->elements memory) can be out of date.
whenChanged/uSNChanged now get added to the msg last, just before the DB
modify operation. So old_el can no longer become out of date within
replmd_process_link_attribute(), so re-fetching it is now redundant.

Move this closer to where the source object actually gets modified.
The main reason to do this is that adding fields can cause the

Commit 775054afbe reworked replmd_process_link_attribute() so that
we batch together DB operations for the same source object. However, it
was possible that the object had not actually changed at all, e.g.
- link was already processed by critical-objects-only during join, or
- we were doing a full-sync and processing info that was already
up-to-date in our DB.
In these cases we modified the object anyway, even though nothing had
changed. This patch fixes it up, so we check that the object has
actually changed before modifying the DB.

In order to share work across related link attribute updates, we need
replmd_process_link_attribute() to let the caller know what actually
changed.
This patch adds an extra return type that'll be used in the next patch.
What we're interested in is: the update was ignored (i.e. it's old news),
a new link attribute was added (because this affects the overall
msg/element memory), and an existing link attribute was modified (due to
how links are actually stored, this includes deleting the link, as in
reality it simply involves setting the existing link to 'inactive').

By caching the recycle-bin state we can save ~6% of the join time.
Checking whether the recycle-bin is enabled involves an underlying DSDB
search. We do this ~4 times for each link we replicate (twice for the
link source and target). By caching the recycle-bin's state over the
duration of the replication, we can save 1000s of unnecessary DB
searches.
With 5K users this makes the join time ~5 secs faster.
