Auto-PTR (and --ptr) changed PTR records in every linked view, whatever
view the address record was in. ptrSync now compares each touched A/AAAA
set before and after, per view, and changes only that view's reverse
zone. PTR records in linked reverse zones are local (fill too); a shared
PTR set is made local in each view before one view changes it.
Deleting a linked zone's local records no longer brings the shared ones
back into the view: the name and type are gone from that view and the
other views keep theirs, local to each. Share still restores.
