Allows us to reuse the same code in multiple places, avoiding new and
interesting bugs (the testing framework had a DIY version that was slightly
wrong, for example). Fixed#9833.

This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering. For the first case, django.test.TransactionTestCase should be used. TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case. See the testing doc for full details.

columns when creating tables. Patch from Ian Kelly.
Columns are NULL by default, so we only need to use "NOT NULL" when we want
non-default behaviour.
