Malcolm Tredinnick d2ce1df08f Fixed #7215 -- Create correct reverse-relation accessors when using abstract base classes. Patch from Joel Watts.

Malcolm Tredinnick ba015e0a79 Fixed #7181 -- when ordering by a potentially NULL field, use a left-outer join
so that the ordering doesn't accidentally restrict the result set.

(Ironically, one existing test actually showed this problem, but I was too
dumb to notice the result was incorrect.)

Malcolm Tredinnick 915001ad0b Fixed #7109 -- Quote certain values before passing them for substitution in
Field.db_type().

This fixes a problem with using reserved words for field names in Oracle. Only
affects Oracle at the moment, but the same changes could easily be used by
other backends if they are required (requires changing creation.py, only).

This commit also reverts [7501] so that if the fix doesn't work, it will show
up in the tests (and if it does work, the tests will prevent us from breaking
it again).

Malcolm Tredinnick 002dbd16b4 Removed the bulk of the sanity checking when merging QuerySets.
It was causing too many inconvenient and unintended problems when merging
legitimate subclasses (e.g. with geo-django classes). There's still a hook
there that we use when merging ValueQuerySets, but if you try to merge two
disparate QuerySets and it breaks all that happens is you get to keep both
pieces. We're no longer penalising the useful usages just for the people who
aren't concentrating.

Fixed #7113.

Malcolm Tredinnick 588eeb356c Fixed a problem when constructing complex select_related() calls.
Avoids joining with the wrong tables when connecting select_related() tables to
the main query. This also leads to slightly more efficient (meaning less tables
are joined) SQL queries in some other cases, too. Some unnecessary tables are
now trimmed that were not previously.

Malcolm Tredinnick 1834428648 Fixed a problem with values() and values_list() queries and nullable joins.
Previously, if we were querying across a nullable join and then a non-nullable
one, the second join would not be a LEFT OUTER join, which would exclude
certain valid results from the result set.

This is the same problem as [7597] but for values() field specifications, so
this covers the second case where Django adds extra stuff to the select-clause.

Russell Keith-Magee 12716794db Fixed #7350, #7202 -- Fixed serialization for multi-model inheritance, which had multiple problems:
* Serializers were including all superclass fields in their output. Now only local fields are included.
 * Implicit OneToOne primary keys were not correctly added to the metamodel, so they were always marked to be serialized, even though they were primary
 * Model saving was too aggressive about creating new parent class instances during deserialization. Raw save on a model now skips saving of the parent class.

Malcolm Tredinnick 6a796690e6 It makes sense that when you subclass an existing model field, you're often
going to be using the same database column type. Made that properly
inheritable (previously it was using the class name), at the cost of a little
more verboseness.

This is very slightly backwards incompatible (for subclasses of existing fields
that were relying on the old default).
