Convert internal error/warning handling framework to a new unified system
Replace the ad hoc error and warning handling with a new system that
codifies the errors with specific codes. This makes it possible in the
future for error numbers to be used for testing and other purposes. It also
makes sure the error strings themselves are consistent.
Thanks to Erik G <erik@6809.org> for the patch.
