* The new method uses an admin configuration option (`formfield_overrides`); this makes custom admin widgets especially easy.
* Refactored what was left of `formfield_for_dbfield` into a handful of smaller methods so that it's easier to hook in and return custom fields where needed.
* These `formfield_for_*` methods now pass around `request` so that you can easily modify fields based on request (as in #3987).
Fixes#8306, #3987, #9148.

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:

This *is* backwards compatible, but `admin.site.root()` has been deprecated. The new style is `('^admin/', include(admin.site.urls))`; users will need to update their code to take advantage of the new customizable admin URLs.
Thanks to Alex Gaynor.

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.

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.

Astute readers will notice that the patch originally called this `default`; after consideration I decided that `empty` is a very slightly better color for this particular bikeshed.

passed in for the connector. This was contrary to what the documentation
for autoescaping said and to what every other filter does with literal
strings as arguments.
This is backwards incompatible for the situation of the literal string
containing one of the five special HTML characters: if you were writing
{{ foo|join:"&" }}, you now have to write {{ foo| join:"&" }}.
Previous behaviour was, as noted, a bug and contrary to what was
documented and expected.

This case pops up with generic foreign key inlines after [9297]. Added tests
to handle future regressions with generic foreign key inlines in the admin.
