In bug #14300 it's pointed out that cube_in rejects zero-element
cubes, as well as infinity and NaN coordinate values.  Since it's
easy to make such cube values via the cube-from-float-array
constructors, this is a dump/reload hazard.  The attached proposed
patch attempts to fix it up.

To deal with the infinity/NaN issues, I made cube_in and cube_out rely
on float8in_internal and float8out_internal, as we recently did for the
core geometric types.  That causes the response to "1e-700" to be an
out-of-range error rather than silent underflow, which seems to me to
be fine, especially since it removes the platform dependency that's
responsible for needing the separate cube_1.out and cube_3.out files.

I also took the opportunity to make cube_in's error strings and ERRCODE
results match project convention.  This is maybe a bit more debatable,
but I think it's worth doing as long as we're touching the function's
behavior.

I found only one other place that seemed to be assuming that cubes
aren't zero-length, but it would be worth someone reviewing it again
to see if I missed anything.  I'll put this on the commitfest queue.

                        regards, tom lane
