Move db_post_events(waveform, NORD) into recordType.

Dirk pointed out that existing device support authors aren't
going to add this themselves; it's much better if the record
does it all for itself.

<h3>Post events on Waveform record's NORD field</h3>
<p>When the record type or soft device support modify the NORD field of a
waveform record they now also post a DBE_VALUE and DBE_LOG event, signalling the
array length change to any clients monitoring the NORD field. Input device
support routines should be modified to do this as well.</p>
