This deprecates forcing a return value for ArrayAgg, JSONBAgg, and
StringAgg when there are no rows in the query. Now that we have a
``default`` argument for aggregates, we want to revert to returning the
default of ``None`` which most aggregate functions return and leave it
up to the user to decide what they want to be returned by default.
Whether or not the state of a test database should be serialized can be
inferred from the set of databases allowed to be access from discovered
TestCase/TransactionTestCase enabling the serialized_rollback feature
which makes this setting unnecessary.
This should make a significant test suite bootstraping time difference
on large projects that didn't explicitly disable test database
serialization.
This also replaces assertQuerysetEqual() to
assertSequenceEqual()/assertCountEqual() where appropriate.

It's a transitional setting helpful in migrating multiple instance of
the same project to Django 3.1+.
Thanks Markus Holtermann for the report and review, Florian
Apolloner for the implementation idea and review, and Carlton Gibson
for the review.
Since it's introduction in Django 1.8 setUpTestData has been suffering
from a documented but confusing caveat due to its sharing of attributes
assigned during its execution with all test instances.
By keeping track of class attributes assigned during the setUpTestData
phase its possible to ensure only deep copies are provided to test
instances on attribute retreival and prevent manual setUp gymnastic to
work around the previous lack of in-memory data isolation.
Thanks Adam Johnson for the extensive review.
The {% if %} tag provides all features of these tags.
Since Django 1.2 (May 17, 2010), the docs have hinted that
{% ifequal %} and {% ifnotequal %} will be deprecated in a future
Django version. Time to make it official.
Thanks to Adam Johnson, Carlton Gibson, Mariusz Felisiak, and Raphael
Michel for mentoring this Google Summer of Code 2019 project and
everyone else who helped with the patch.
Special thanks to Mads Jensen, Nick Pope, and Simon Charette for
extensive reviews.

Now that order_by() has expression support passing RawSQL() can achieve
the same result.
This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.
This is the new contract since middleware refactoring in Django 1.10.

The function was undocumented and only required for compatibility with
Python 2.
Code should use Python's html.unescape() that was added in Python 3.4.
