22ecacda1b queryset-refactor: Fixed a small error in [7179].

fa11a6a128 queryset-refactor: Fixed a problem in the test-suite that was annoying. 
Only fails on PostgreSQL and only fails on the next test.

Also identified the other area that causes both PostgreSQL backends (only) to
fail. Don't really understand why at the moment, but this is the culprit.
Tricky to reproduce, too, you have to run "queries" and "views" together, in
that order to see it.

7c54780497 queryset-refactor: Head off any attempts to use unique_together across inherited models. 
We don't support check constraints and triggers, so trying to do this would be
optimistic at best.

a9008f8928 queryset-refactor: Added caching for reverse-one-to-one lookups. 
This is the only type of reverse lookup where caching makes sense might make
some kinds of model inheritance interactions more database friendly.

33a0862215 queryset-refactor: Fixed exclude() filtering for the various N-to-many relations. 
This means we can now do nested SQL queries (since we need nested queries to
get the right answer). It requires poking directly at the Query class. Might
add support for this through QuerySets later.

014373b459 queryset-refactor: Fixed #6664. Calling list() no longer swallows field errors. 
This is slightly backwards incompatible with previous behaviour if you were
doing Tricky Stuff(tm) -- the exception type has changed if you try to create a
bad queryset.

da6570bf08 queryset-refactor: Model inheritance support. 
This adds both types of model inheritance: abstract base classes (ABCs) and
multi-table inheritance. See the documentation and tests / examples for details.

Still a few known bugs here, so don't file tickets (I know about them). Not
quite ready for prime-time usage, but it mostly works as expected.

accc20d799 queryset-refactor: Fixed up OneToOneFields (mostly). 
They now share as much code as possible with ForeignKeys, but behave more or
less as they did before (the backwards incompatible change is that they are no
longer automatically primary keys -- so more than one per model is permitted).

The documentation still uses an example that is better suited to model
inheritance, but that will change in due course. Also, the admin interface
still shows them as read-only fields, which is probably wrong now, but that can
change on newforms-admin after this branch is merged into trunk.

class over to use queryset operations. This is the first part of a long process
of removing raw SQL from all over the place. The tests pass, but it's quite
possible other stuff won't work yet.

In the process, added tests for order_with_respect_to so that I didn't screw it
up.

de94d0cb93 queryset-refactor: Added an update method to QuerySets, since it's needed for 
moving SQL out of the core code. Only direct fields and foreign keys can be
updated in this fashion, since multi-table updates are very non-portable.

This also cleans up the API for the UpdateQuery class a bit. Still need to
change DeleteQuery to work similarly, I suspect.

Refs #4260.

dd2251a653 queryset-refactor: Converted the queryset iterator to be a real iterator and 
only populate the result cache on demand. We actually populate the result cache
100 elements at a time, rather than one at a time for efficiency, but this is a
real win when the resultset contains 10,000 objects for example.

This also provides an efficient boolean (__nonzero__) test that doesn't use up
a lot of memory if you don't read all the results.
