This patch removes a lot of unused code related to assertions and

error handling, and simplifies the code that remains. Apparently,
the code that left Berkeley had a whole "error handling subsystem",
which exceptions and whatnot. Since we don't use that anymore,
there's no reason to keep it around.

The regression tests pass with the patch applied. Unless anyone
sees a problem, please apply.
