In extreme cases, some fields are expensive to load from the database

commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Malcolm Tredinnick f747b61c20 Nested query support.
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.

Malcolm Tredinnick 062a94ef45 Reconciling where- and having-clause behaviour.
Extricated the code that works directly with SQL columns (standard
"where" stuff) from the the code that takes SQL fragments and combines
it with lookup types and values. The latter portion is now more
generally reusable. Any existing code that was poking at Query.having
will now break in very visible ways (no subtle miscalculations, which is
a good thing).

This patch, en passant, removes the existing "having" test, since the
new implementation requires more setting up than previously. The
aggregates support (currently in a separate codebase) has tests for this
functionality that work as a replacement for the removed test.

Malcolm Tredinnick a1cbeb9afb If an SQL query doesn't specify any ordering, avoid the implicit sort
that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

Malcolm Tredinnick 44f228fd61 Fixed #6748 -- When printing the repr() of querysets, don't load or display

This means that accidentally executing HugeStoryArchive.objects.all() at the
interactive prompt (or in the debug template) won't try to load all 4,233,010
stories into memory and print them out. That would previously cause resource
starvation and other "interesting" crashes.

If you really, really want the previous behaviour (e.g. in a doctest that
prints more than 20 items), display "list(qs)" instead of just "qs".

Malcolm Tredinnick e47cc781d8 A bug from queryset-refactor days: although the Query class has "group_by" and
