Thanks Aymeric Augustin for review.

The method duplicates the functionality of Field.value_from_object()
and has the additional downside of being a privately named public
API method.

Thanks Jaap Roes for completing the patch.

Setup QUnit, added tests, and measured test coverage.

Thanks to Nick Sanford for the initial tests.

Forwardport of ae1d663b
from stable/1.8.x plus more.

Made URL application namespaces be set in the included URLconf and
instance namespaces in the call to include(). Deprecated other ways
to set application and instance namespaces.

Renamed the mime_type properties of RssFeed and Atom1Feed to
content_type and start deprecation for the old names.

Refs #23820.

Fixed #19738.

Refs #17755. In order not to introduce a regression for raw queries,
parameters are passed through the connection.ops.value_to_db_* methods,
depending on their type.

Thanks Tim Graham for the review.
