Error level constants cannot be used in settings.php

This should do it.

If I'm not mistaken, then we have a test somewhere that checks for exact line numbers in errors.inc (which was the original reason for splitting that code out of frequently changed files such as bootstrap.inc and common.inc), so this change might trigger a test failure.

#1: drupal8.error-constants.1.patch queued for re-testing.

So this patch actually passed should be RTBC if it still comes back green.

heh. :)

Thanks!
