Allow empty APL records

Browse source 
Allow empty APL records because RFC 3123 (Section 4) says "zero or
more items". This fixes processing of a catalog zone ACL (which is
based on APL records) when the zone contains an empty APL record or
when a zone update arrives which creates an empty APL record.
