Adrian Holovaty 6ff118cdb9 Fixed #17644 -- Changed Query.alias_map to use namedtuples
This makes the code easier to understand and may even have a benefit in memory usage (namedtuples instead of dicts). Thanks, lrekucki and akaariai

Claude Paroz 3904b74a3f Fixed #18013 -- Use the new 'as' syntax for exceptions.
Thanks Clueless for the initial patch.
Note that unittest has been purposely left out (external package only used by Python 2.6).

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.
