Aymeric Augustin 91e9f1c972 Fixed #24921 -- set_autocommit(False) + ORM queries.
This commits lifts the restriction that the outermost atomic block must
be declared with savepoint=False. This restriction was overly cautious.

The logic that makes it safe not to create savepoints for inner blocks
also applies to the outermost block when autocommit is disabled and a
transaction is already active.

This makes it possible to use the ORM after set_autocommit(False).
Previously it didn't work because ORM write operations are protected
with atomic(savepoint=False).

==========================
Django 1.8.5 release notes
==========================
*Under development*
Django 1.8.5 fixes several bugs in 1.8.4.
Bugfixes
========
* Made the development server's autoreload more robust (:ticket:`24704`).
* Fixed ``AssertionError`` in some delete queries with a model containing a
field that is both a foreign and primary key (:ticket:`24951`).
* Fixed ``AssertionError`` in some complex queries (:ticket:`24525`).
* Fixed a migrations crash with ``GenericForeignKey`` (:ticket:`25040`).
* Made ``translation.override()`` clear the overridden language when a
translation isn't initially active (:ticket:`25295`).
* Fixed crash when using a value in ``ModelAdmin.list_display`` that clashed
with a reverse field on the model (:ticket:`25299`).
* Fixed autocompletion for options of non-``argparse`` management commands
(:ticket:`25372`).
* Alphabetized ordering of imports in ``from django.db import migrations,
models`` statement in newly created migrations (:ticket:`25384`).
* Fixed migrations crash on MySQL when adding a text or a blob field with an
unhashable default (:ticket:`25393`).
* Changed ``Count`` queries to execute ``COUNT(*)`` instead of ``COUNT('*')``
as versions of Django before 1.8 did (:ticket:`25377`). This may fix a
performance regression on some databases.
* Fixed custom queryset chaining with ``values()`` and ``values_list()``
(:ticket:`20625`).
* Moved the :ref:`unsaved model instance assignment data loss check
<unsaved-model-instance-check-18>` on reverse relations to ``Model.save()``
(:ticket:`25160`).
* Readded inline foreign keys to form instances when validating model formsets
(:ticket:`25431`).
* Allowed using ORM write methods after disabling autocommit with
:func:`set_autocommit(False) <django.db.transaction.set_autocommit>`
(:ticket:`24921`).
