Tracking column-level ACL dependencies rather than having those
dependencies only be at the table-level.  This complicates
pg_shdepend some, but simplifies the dependency handling in the
ACL area and in handling table/column drops.

I'm still not a fan of having column-level deps handled
differently between pg_shdepend and pg_depend, but that's not
something which has to be addressed directly by the column-level
privs patch.  Perhaps once it's done I'll do a proof-of-concept
for removing pg_attdef.
