Some more editing of the range-types documentation.
...
Be more thorough about specifying the expectations for canonical and
subtype_diff functions, and move that info to the same place.

Remove zero- and one-argument range constructor functions.
...
Per discussion, the zero-argument forms aren't really worth the catalog
space (just write 'empty' instead). The one-argument forms have some use,
but they also have a serious problem with looking too much like functional
cast notation; to the point where in many real use-cases, the parser would
misinterpret what was wanted.
Committing this as a separate patch, with the thought that we might want
to revert part or all of it if we can think of some way around the cast
ambiguity.

Adjust range type docs for some last-minute changes I made to the patch.
...
non_empty(anyrange) function was removed, empty(anyrange) was renamed to
isempty(anyrange), and !? operators were removed.

Support range data types.
...
Selectivity estimation functions are missing for some range type operators,
which is a TODO.
