Fix the built-in GIN support procedure declarations in pg_proc.h.
Fix the built-in GIN support procedure declarations in pg_proc.h.

Add more "internal" arguments so that these pg_proc entries reflect the
current preferred API.  This is purely a cosmetic change, since GIN doesn't
actually consult the pg_proc entry when calling a support function.
Accordingly, no catversion bump.
