When a GenericRelation was defined on abstract model, queries on childs
of the abstract model didn't work. The problem was in the way fields and
in particular field.rel was copied from models to their children.

The regression was likely caused by #19385. Thanks to Gavin Wahl for
spotting the regression.

Fix typo in redirect view docs

Changed API to disable ATOMIC_REQUESTS per view.

The failure was caused by generating the same warning from two tests.
The second time the same warning was raised it was swallowed by the
"once" simplefilter of warnings.

A decorator is easier to apply to CBVs. Backwards compatibility isn't an
issue here, except for people running on a recent clone of master.

Fixed a few minor problems in the transactions docs while I was there.

Thanks Jérémie Blaser.

Thanks to guettli for the initial ticket and patch, with additional work
from mehmetakyuz and Kevin Brolly.

Thanks Claes Ström for the patch.

Thanks Tomasz Jaskowski for the patch.

Fix for test failure introduced by 980ae2ab.

Thanks to Daniele Procida for help with the docs.

Thanks Shai Berger for the report.

This commit also adds tests for the redirect feature of most auth views.
It also cleans up the tests, most notably using @override_settings instead
of ad-hoc setUp/tearDown methods.

Thanks to caumons for the report.
