It rarely hurts to think of the returned result from a values() or
values_list() call as a list, but it's really an iterable and sometimes
the difference matters.

This monster of a patch is the result of Alex Gaynor's 2009 Google Summer of Code project.
Congratulations to Alex for a job well done.
Big thanks also go to:
* Justin Bronn for keeping GIS in line with the changes,
* Karen Tracey and Jani Tiainen for their help testing Oracle support
* Brett Hoerner, Jon Loyens, and Craig Kimmerer for their feedback.
* Malcolm Treddinick for his guidance during the GSoC submission process.
* Simon Willison for driving the original design process
* Cal Henderson for complaining about ponies he wanted.
... and everyone else too numerous to mention that helped to bring this feature into fruition.

In the future, I'd like to fix this properly, but the current behavior
has the advantage of being consistent across the board (and changing it
everywhere is backwards-incompatible with documented functionality).

In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Previous behaviour was pretty stupid. Let's never speak of it again. New
behaviour both works and is documented.

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.

Other, more minor ones, were removed altogether.
Based on a patch from James Bennett.

These were accidentally nuked in the docs refactor. We know who the offenders
were. They will be made to sit in the corner on the naughty mat for a while.

This describes values_list(), the new cross-model order_by() syntax and the
effects of distinct(), values() and order_by() on each other.

Backwards incompatible if you are using manually-specific primary key values
and relying on the previously documented behaviour that the new values would
always exist in the database (i.e. it would update the existing entry).
Fixed#8419.
