Remove useless/superfluous Datum conversions

Browse Source 
Remove useless DatumGetFoo() and FooGetDatum() calls.  These are
places where no conversion from or to Datum was actually happening.

We think these extra calls covered here were harmless.  Some actual
bugs that were discovered during this process have been committed
separately (80c758a2e1, 2242b26ce4).
