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).

Not sure if any of these are noticed as omissions yet; it's too new.
Primarily trying to head off questions in the future.

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.

These features look similar, but they're not identical. They can't be merged
into one (without requiring at least two Meta parameters anyway), so we've made
them have APIs that match their natural use-cases most easily.
Anyway, the documentation explains both the details and gives some simple to
follow rules.

Large portions of this are needed for #5420, so I implemented it fully.
Thanks to Ryan Kelly for an initial patch to get this started.
Refs #5420.

This allows a model to be defined which is not subject to database table
creation and removal. Useful for models that sit over existing tables or
database views.
Thanks to Alexander Myodov, Wolfgang Kriesing and Ryan Kelly for the bulk of
this patch.

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.

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.
