Further consolidation of DROP statement handling.

Browse Source 
This gets rid of an impressive amount of duplicative code, with only
minimal behavior changes.  DROP FOREIGN DATA WRAPPER now requires object
ownership rather than superuser privileges, matching the documentation
we already have.  We also eliminate the historical warning about dropping
a built-in function as unuseful.  All operations are now performed in the
same order for all object types handled by dropcmds.c.
