Also added a section to the documentation to indicate why it's probably not a
good idea to rely on this feature for complex stuff. Garbage in, garbage out
applies even to Django code.
Thanks to erik for the test case for this one.

Patch from mturtle@gmail.com. The remaining uses of "%s__pk" in
fields/related.py all look safe, since they are for many-to-many fields, which
doesn't take "to_field" as a parameter.

When model inheritance is used, the parent objects should be deleted as part of
the delete() call on the child.

The previous change was failing Django's "check for well-formed domain name"
validation, rather than failing on the network side. Providing we don't ever
set up www.broken.djangoproject.com as a valid domain name, this change should
let us control our own destiny.

We no longer store any reference to Django field instances or models in the
Where node. This should improve cloning speed, fix some pickling difficulties,
reduce memory usage and remove some infinite loop possibilities in odd cases.
Slightly backwards incompatible if you're writing custom filters. See the
BackwardsIncompatibleChanges wiki page for details.
Fixed#7128, #7204, #7506.

These types of relations don't have reverse accessor names, so that name can be
used by a normal field on the model. Fixed#7107.

so that the ordering doesn't accidentally restrict the result set.
(Ironically, one existing test actually showed this problem, but I was too
dumb to notice the result was incorrect.)

Field.db_type().
This fixes a problem with using reserved words for field names in Oracle. Only
affects Oracle at the moment, but the same changes could easily be used by
other backends if they are required (requires changing creation.py, only).
This commit also reverts [7501] so that if the fix doesn't work, it will show
up in the tests (and if it does work, the tests will prevent us from breaking
it again).

Avoids joining with the wrong tables when connecting select_related() tables to
the main query. This also leads to slightly more efficient (meaning less tables
are joined) SQL queries in some other cases, too. Some unnecessary tables are
now trimmed that were not previously.

Previously, if we were querying across a nullable join and then a non-nullable
one, the second join would not be a LEFT OUTER join, which would exclude
certain valid results from the result set.
This is the same problem as [7597] but for values() field specifications, so
this covers the second case where Django adds extra stuff to the select-clause.

* Serializers were including all superclass fields in their output. Now only local fields are included.
* Implicit OneToOne primary keys were not correctly added to the metamodel, so they were always marked to be serialized, even though they were primary
* Model saving was too aggressive about creating new parent class instances during deserialization. Raw save on a model now skips saving of the parent class.

* Raise a ValueError if you try to assign the wrong type of object.
* Raise a ValueError if you try to assign None to a field not specified with null=True.
* Cache the set value at set time instead of just at lookup time.
This is a slightly backwards-incompatible change; see BackwardsIncompatibleChanges for more details.
