Previous behaviour was pretty stupid. Let's never speak of it again. New
behaviour both works and is documented.

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.
Many thanks to:
* Marc Remolt for the initial proposal and implementation.
* Luke Plant for initial testing and improving the implementation.
* Ramiro Morales for feedback and help with tracking down a mysterious PostgreSQL issue.
* Eric Holscher for feedback regarding the effect of the change on the Ellington testsuite.
* Russell Keith-Magee for guidance and feedback from beginning to end.

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.

This extends previous functionality that allowed passing Query objects as the
rvals to filters. You can now pass QuerySets, which requires less poking at
opaque attributes. See the documentation of the "__in" lookup type for the
details.

Extricated the code that works directly with SQL columns (standard
"where" stuff) from the the code that takes SQL fragments and combines
it with lookup types and values. The latter portion is now more
generally reusable. Any existing code that was poking at Query.having
will now break in very visible ways (no subtle miscalculations, which is
a good thing).
This patch, en passant, removes the existing "having" test, since the
new implementation requires more setting up than previously. The
aggregates support (currently in a separate codebase) has tests for this
functionality that work as a replacement for the removed test.

The last use of it was removed in r9641 (it's internal API) and it's been
broken since r7477, as there's no longer a maximum of one OneToOneField per
model, so anything relying on it contained subtle bugs.

that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

lookup in the serializable_value() method. This means that abstract
parents that are multi-table children of other models(no, really!!) now
work again.

"value" for a field that is a relation to another model.
This part adds the utility method on Model that should help in general.Also
cleans up the slightly ugly mess from r8957.

Descriptors now return themselves when accessed via the class, as per standard
Python descriptors like property().
