Minor catalog cleanups for composite-type stuff. Adjust signatures shown

in pg_proc for record_in, record_out, etc to reflect that these routines
now make use of the second OID parameter.  Remove the ancient SET entry
in pg_type, which is now highly unlikely to ever become used again.
Adjust type_sanity regression test to match.
