Remove unimplemented/undocumented geometric functions & operators.

Nobody has filled in these stubs for upwards of twenty years,
so it's time to drop the idea that they might get implemented
any day now.  The associated pg_operator and pg_proc entries
are just confusing wastes of space.

Per complaint from Anton Voloshin.
