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.

Anssi Kääriäinen 8c72aa2379 Fixed qs.order_by() join promotion for already existing joins
When order_by causes new joins to be added to the query, the joins must
be LEFT OUTER joins for nullable relations, otherwise the order_by
could cause the results to be altered. This commit fixes the logic to
only promote new joins, previously all joins in the order_by lookup
path were promoted.

Thanks to Bruno Desthuilliers for spotting this corner case.

Claude Paroz df7a65ac4b Replaced 'next' testing by collections.Iterator testing.
The new construct is also Python 3 compatible (where 'next' has
been renamed to '__next__').

Anssi Kääriäinen d5c7f9efc3 Fixed #18304 -- Optimized save() when update_can_self_select=False
Databases with update_can_self_select = False (MySQL for example)
generated non-necessary queries when saving a multitable inherited
model, and when the save resulted in update.

Claude Paroz 169b1a404c Replaced foo.next() by next(foo).
This new syntax for next() has been introduced in Python 2.6 and is
compatible with Python 3.

Anssi Kääriäinen c2e1ecb4b1 Fix proxy model Query.remove_inherited_models()
Fixed #18248 -- proxy models were added to included_inherited_models
in sql.query.Query. The variable is meant to be used for multitable
inheritance only. This mistake caused problems in situations where
proxy model's query was reused.

Anssi Kääriäinen 584e2c0337 Prevent Oracle from changing field.null to True
Fixed #17957 -- when using Oracle and character fields, the fields
were set null = True to ease the handling of empty strings. This
caused problems when using multiple databases from different vendors,
or when the character field happened to be also a primary key.

The handling was changed so that NOT NULL is not emitted on Oracle
even if field.null = False, and field.null is not touched otherwise.

Thanks to bhuztez for the report, ramiro for triaging & comments,
ikelly for the patch and alex for reviewing.

Anssi Kääriäinen 5aa51fa999 Simplified QuerySet field.null handling
QuerySet had previously some complex logic for dealing with nullable
fields in negated add_filter() calls. It seems the logic is leftover
from a time where the WhereNode wasn't as intelligent in handling
field__in=[] conditions.

Thanks to aaugustin for comments on the patch.

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 c3a0dcf6e9 Added convenience method for viewing Query SQL without params.
This is the old Query.as_sql() method revived: it's like Query.__str__,
but the parameters aren't substituted into the placeholders. Thus, it's
a more accurate representation of the SQL the (default) backend will
see. Entirely internal.

Jacob Kaplan-Moss fd2f18008c Fixed #14733: no longer "validate" .raw() queries.
Turns out that a lot more than just SELECT can return data, and this list is
very hard to define up front in a cross-database manner. So let's just assume
that anyone using raw() is at least halfway competant and can deal with
the error messages if they don't use a data-returning query.

Thanks to Christophe Pettus for the patch.
