This restores filtering on dates in the admin, for example. Thanks to akfarrell
and a small team of workers at the Portland Sprint.

fields no longer creates duplicate copies of the join table(s). Basically, this
means filters on the join table (for ManyToManyField(through=...)) and complex
filters in the normal (non-through) case don't produce incorrect or duplicate
results.

environment doesn't support os.listdir(), we crashed whilst trying to construct
the friendly error message. This was not so friendly.
This patch handles that case (which occurs in real life in Google App Engine).
Patch from Guido van Rossum.

code. As pointed out in the ticket, Python still lets you raise all sorts of
odd things as exceptions (e.g. strings), so even though they're bad form, we
should still handle them. We do that cleanly now. Thanks to jim-django@dsdd.org
for the patch.

transaction (after another exception in the code), make sure the original
exception is reported, rather than the rollback-generated one. The latter is
almost certainly a consequence of the former. Patch from Karen Tracey.

This effectively reverses the change in [7798]. It was proving too difficult to
successfully manage all the side effects here and provide a satisfactory
solution for everybody. Many thanks to arne, Martin von Löwis and, particular,
Karen Tracey, for doing a lot of research and proto-patches here to establish what was possible and practical.
This is backwards incompatible if you were relying on the behaviour after
[7798]. The docs have been updated to indicate the solution.

Fixed#7402.
Also made savepoint handling easier to use when wrapped around calls that might
commit a transaction. This is tested by the get_or_create tests.

This is a no-op for most databases. Only necessary on PostgreSQL so that we can
do things which will possibly intentionally raise an IntegrityError and not
have to rollback the entire transaction. Not supported for PostgreSQL versions
prior to 8.0, so should be used sparingly in internal Django code.

* Support for representing files as strings was removed. Use `django.core.files.base.ContentFile` instead.
* Support for representing uploaded files as dictionaries was removed. Use `django.core.files.uploadedfile.SimpleUploadedFile` instead.
* The `filename`, `file_name`, `file_size`, and `chuck` properties of `UploadedFile` were removed. Use the `name`, `name`, `size`, and `chunks` properties instead, respectively.
* The `get_FIELD_filename`, `get_FIELD_url`, `get_FIELD_size`, and `save_FIELD_file` methods for Models with `FileField` fields were removed. Instead, use the `path`, `url`, and `size` attributes and `save` method on the field itself, respectively.
* The `get_FIELD_width` and `get_FIELD_height` methods for Models with `ImageField` fields were removed. Use the `width` and `height` attributes on the field itself instead.
* The dispatcher `connect`, `disconnect`, `send`, and `sendExact` functions were removed. Use the signal object's own `connect`, `disconnect`, `send`, and `send` methods instead, respectively.
* The `form_for_model` and `form_for_instance` functions were removed. Use a `ModelForm` subclass instead.
* Support for importing `django.newforms` was removed. Use `django.forms` instead.
* Support for importing `django.utils.images` was removed. Use `django.core.files.images` instead.
* Support for the `follow` argument in the `create_object` and `update_object` generic views was removed. Use the `django.forms` package and the new `form_class` argument instead.

searching within a field column (e.g. "like", "contains", etc). Required for
PostgreSQL 8.3. Thanks to Dan Watson for the patch.

Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes.
Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated.
Documentation is, sigh, still forthcoming.
Fixes#6814 and #3951 (with the new dispatch_uid argument to connect).

* Model init no longer performs a database query to refetch the related objects it is passed.
* Model init now caches unsaved related objects correctly, too. (Previously, accessing the field would raise `DoesNotExist` error for `null=False` fields.)
* Added tests for assigning `None` to `null=True` `ForeignKey` fields (refs #6886).
