Preston Holmes 965cc0b1ff Deprecated depth kwarg on select_related.
This is the start of a deprecation path for the depth kwarg on
select_related. Removing this will allow us to update select_related so
it chains properly and have an API similar to prefetch_related.

Thanks to Marc Tamlyn for spearheading and initial patch.

Anssi Kääriäinen 1cd6e04cd4 Fixed #18676 -- Allow fast-path deletion of objects
Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.

Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing
the patch.

Andrei Antoukh 99321e30ce Fixed #18306 -- Made deferred models issue update_fields on save
Deferred models now automatically update only the fields which are
loaded from the db (with .only() or .defer()). In addition, any field
set manually after the load is updated on save.

Anssi Kääriäinen 29132ebdef Fixed #17788 -- Added batch_size argument to qs.bulk_create()
The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.

Thanks to everybody who participated in the discussions at Trac.

Anssi Kääriäinen b6c356b7bb Fixed #17485 -- Made defer work with select_related
This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.

Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.

A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.

Ramiro Morales 287565779d Added support for modifying the effect of ``DISTINCT`` clauses so they
only consider some fields (PostgreSQL only).

For this, the ``distinct()`` QuerySet method now accepts an optional
list of model fields names and generates ``DISTINCT ON`` clauses on
these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work.

Fixes #6422.

Malcolm Tredinnick 4c8f2dca21 Extensive copy-editing and cross-referencing in the queryset API docs.
Been meaning to do this for a long time. Mostly, this is a lot of
additions of cross references. Within a particular section about foo() I
didn't cross-link foo() calls to itself, but everything else was
cross-linked to its main documentation.
