Malcolm Tredinnick baa960209f Fixed Queryset.dates() in the presence of extra-select columns. 
Any extra(select=...) columns can be ignored in the SQL for dates, since we are
only interested in extracting distinct date values. We were previously
including them by accident and it was generating incorrect SQL.

Malcolm Tredinnick cfcfc456e9 Fixed a typo so that cloning UpdateQuery objects won't fail mysteriously.

Malcolm Tredinnick dc14b29fb3 Added the ability to force an SQL insert (or force an update) via a model's 
save() method.

Malcolm Tredinnick 6dd2b5468f Redo the changes in [7773] in a better way. 
This removes some of the leaky abstraction problems (lifting WhereNode
internals into the Query class) from that commit and makes it possible for
extensions to WhereNode to have access to the field instances. It's also
backwards-compatible with pre-[7773] code, which is also better.

Malcolm Tredinnick ade4a1246c Reorganised the internals of the Where node a bit to fix some copying problems. 
We no longer store any reference to Django field instances or models in the
Where node. This should improve cloning speed, fix some pickling difficulties,
reduce memory usage and remove some infinite loop possibilities in odd cases.
Slightly backwards incompatible if you're writing custom filters. See the
BackwardsIncompatibleChanges wiki page for details.

Fixed #7128, #7204, #7506.

Malcolm Tredinnick ba010ec1c0 Made some types of nested update queries very slightly more efficient at the 
database level. Also worked around the fact that MySQL (and maybe other
backends we don't know about) cannot select from the table they're updating.

Fixed #7095.

Adrian Holovaty d649d0f5f8 Fixed #7097 -- dates() queries now work as expected with select_related() -- that is, select_related() has no effect on the query. Thanks for reporting, Marco

Malcolm Tredinnick 9c52d56f6f Merged the queryset-refactor branch into trunk. 
This is a big internal change, but mostly backwards compatible with existing
code. Also adds a couple of new features.
