Russell Keith-Magee cf08ea496e [1.1.X] Refs #13227 -- Partial backport of r12865; backported the changes to Where tree cloning logic to ensure that unclonable objects in a where() clause don't break querying.

Joseph Kocherhans 55bcc8ac30 [1.1.X] Fixed #12734. Deferred fields will now be properly converted to python when accessed. Backport of r12579 from trunk.

Russell Keith-Magee 3bda1f5bd3 [1.1.X] Fixed #6191, #11296 -- Modified the admin deletion confirmation page to use the same object collection scheme as the actual deletion. This ensures that all objects that may be deleted are actually deleted, and that cyclic display problems are avoided. Thanks to carljm for the patch. 
Backport of r12598 from trunk.

Jacob Kaplan-Moss 321fe61f64 [1.1.X] Fixed #11753 - Q objects with callables no longer explode on Python 2.4. Thanks, Jeremy Dunck.

Russell Keith-Magee 2416e5fefe Fixed #9479 -- Corrected an edge case in bulk queryset deletion that could cause an infinite loop when using MySQL InnoDB.

Malcolm Tredinnick dded5f52cc Fixed #10695 -- Fixed implementation of deferred attribute retrieval. 
The original implementation had a few silly bugs in it that meant that data was
not being used only on the instance of the class that it was appropriate for
(one of the traps when using class-level things). No more!

Thanks to Justin Bronn and Alex Gaynor for the patch.

Malcolm Tredinnick 29050ef999 Fixed #5420 -- Added support for delayed loading of model fields. 
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.
