Reverse zones: other views' addresses aren't missing PTRs

A reverse zone's missing PTR count covers only its own view's A and
AAAA records. Addresses only other views' records use are counted apart
(ptr_other_views, 'Other views' in zone show, a note on the zone page)
and filled only when asked: fill-ptr --other-views, zone create
--fill --other-views, or the New reverse zone dialog's checkbox. This
keeps one view's host names out of another view's reverse zones.
