We've discussed this quite a bit already; connecting associated
records into a single event is something that should happen, needs to
happen, and will happen.  Conceptually it makes no sense to record the
syscall (and any other associated records) which triggers the audit
configuration change, and the configuration change record itself as
two distinct events - they are the same event.  We've also heard from
a prominent user that associating records in this way is desirable.

If the ausearch csv and text audit log transformations can't handle
this particular change, I would consider that a shortcoming of that
code.  We have multi-record events now, and this is only going to
increase in the future.

Richard, if you can't make the requested changes to this patch and
resubmit by ... let's say the middle of next week? that should be
enough time, yes? ... please let me know and I'll make the changes and
get this merged.
