Fix #21185: Added tests for unescape_entities.

Also fixed a py3 incompatibility.
Thanks to brutasse for the report.
Fixed malformed directive in CBV date-based-mixins docs.
Fixed #21186: Fixed regression when using date fields in the admin's list_filter.

Thanks to onlygoldi2201 for the report and to ramiro and apollo13
for the reviews.
Fixed #20439 -- Started deprecation of IPAddressField
Fixed #21187 -- Import CursorWrapper from django.db.backend.utils

The import was done from util instead of utils leading to
PendingDeprecationWarning.
Fixed #21162 -- Better emulation of staticfiles middleware.

Code had been added in e909ceae9b. Solves test suite failures observed
on Windows.

Thanks Michael Manfre for the report. Refs #20739.
Note about static files dirs paths on Windows.

Added it to the settings reference. We used to have it in comment form
in our old, bigger default project template settings.py file.
Fixed #20931 -- Fixed select widgets nested choice rendering

ChoiceFieldRenderer was not rendering nested choices. Added recursion
to ChoiceFieldRenderer to take nested choices and render them as
<ul>'s.
Fixed #21167 - Improved queries.tests.SubqueryTests

Improve tests to cover slicing scenarios that could be handled in unique
ways by 3rd party database backends.
Fixed #15786 -- Added a regression test for o2o excludes using F().

The issue was reported against 1.3.x but has been fixed since.
Modified test added in 3afb5916b2 so it doesn't fail on Windows.

Refs #18091.
Fixed #13724: Corrected routing of write queries involving managers.

Previously, if a database request spanned a related object manager, the
first manager encountered would cause a request to the router, and this
would bind all subsequent queries to the same database returned by the
router. Unfortunately, the first router query would be performed using
a read request to the router, resulting in bad routing information being
used if the subsequent query was actually a write.

This change defers the call to the router until the final query is acutally
made.

It includes a small *BACKWARDS INCOMPATIBILITY* on an edge case - see the
release notes for details.

Thanks to Paul Collins (@paulcollinsiii) for the excellent debugging
work and patch.
Fixed #21134 -- Prevented queries in broken transactions.

Squashed commit of the following:

commit 63ddb271a44df389b2c302e421fc17b7f0529755
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Sun Sep 29 22:51:00 2013 +0200

    Clarified interactions between atomic and exceptions.

    Fixed TransactionManagementError in tests.

    Previous commit introduced an additional check to prevent running
    queries in transactions that will be rolled back, which triggered a few
    failures in the tests. In practice using transaction.atomic instead of
    the low-level savepoint APIs was enough to fix the problems.

commit 4a639b059ea80aeb78f7f160a7d4b9f609b9c238
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Tue Sep 24 22:24:17 2013 +0200

    Allowed nesting constraint_checks_disabled inside atomic.

    Since MySQL handles transactions loosely, this isn't a problem.

commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef

    Prevented running queries in transactions that will be rolled back.

    This avoids a counter-intuitive behavior in an edge case on databases
    with non-atomic transaction semantics.

    It prevents using savepoint_rollback() inside an atomic block without
    calling set_rollback(False) first, which is backwards-incompatible in
    tests.

    Refs #21134.

commit 8e3db393853c7ac64a445b66e57f3620a3fde7b0
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Sun Sep 22 22:14:17 2013 +0200

    Replaced manual savepoints by atomic blocks.

    This ensures the rollback flag is handled consistently in internal APIs.
Fixed #21154 -- Updated TemplateResponse docs to better explain context.

Thanks mrmachine for the report.
Fixed Python 3.2 syntax errors; refs #13724.
