Unify drop-by-OID functions

Browse Source 
There are a number of Remove${Something}ById() functions that are
essentially identical in structure and only different in which catalog
they are working on.  Refactor this to be one generic function.  The
information about which oid column, index, etc. to use was already
available in ObjectProperty for most catalogs, in a few cases it was
easily added.
