Manually specifying both a OneToOneField(parent_link=True) and separate a
primary key field was causing invalid SQL to be generated. Thanks to Ramiro
Morales for some analysis on this one.

If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.
Backport of r9966 from trunk (turns out this *is* a bugfix, since the returned
rowcount is used in Model.save(force_update=True)).

This includes a fairly large refactor of the update() query path (and
the initial portions of constructing the SQL for any query). The
previous code appears to have been only working more or less by accident
and was very fragile.

match nothing). This allows for some more straightforward code in the admin
interface.
Fixed#7488 (all the debugging there was done by Brian Rosner, who narrowed it
down to the item in this patch).

key value isn't guaranteed to be the same across all backends). Still some
breakage on MySQL because of the way it treats booleans, but that's another
issue.

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

* 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.
