Similarly to `base_fields` and `hash_fields` it will be easier to
override fields for the search text.

Without this change to add/remove fields from search text we need to
override the `_update_search_text` method.

* Improve efficiency of Range.product_queryset when fetching matching child products.

* Add tests to verify that contains_product returns true for child products whose parent is in a range.

- Add new "DEFAULT_AUTO_FIELD" Django 3.2 setting
- Fix deprecated (in "gettext") use of non-int numbers for selecting
  plural translations
- Provide "get_response" callable when creating middleware-factory
  instance in tests

- This uses a simpler and more robust way to get the list of fields to
  serialise for storage in the session
- "custom_benefit" and "custom_condition" were unused, as they aren't
  fields of any of the serialised models
- Also remove unused parameter in
  "dashboard.offers.views.OfferWizardStepView._fetch_form_kwargs"

- allow creation of offers of all types
- allow creation of vouchers with multiple offers
- allow creation of voucher sets of all usages, and with multiple offers

Issue: https://github.com/django-oscar/django-oscar/issues/3162

* Checking of `offer.benefit.max_affected_items` removed from the
`available` method of `LineOfferConsumer` class - available items should
not be limited by related benefit (it should be considered when applying
the offer).
* Improved `apply` method of `PercentageDiscountBenefit` - affected
items must include "quantities with discount applied".
* `is_satisfied` method of `CountCondition` updated to pass `offer`
instead of `None` to `line.quantity_without_offer_discount` - this
change is required to fix the initial issue.
* Updated `test_available_with_offer` test - initially this test was
added to check the lines that we removed from the `available` method of
`LineOfferConsumer` class (See fda27a183d/).
* Added tests to confirm that the initial issue is fixed.

* Improve `available` method of `LineOfferConsumer` class
* Add `quantity_available_for_offer` method to `AbstractLine` class
* Improve conditions: "Get num matches" methods updated to use `quantity_available_for_offer`
method of `Line` model.
* Improve conditions: `get_upsell_message` methods updated to show upsell message only in
the cases where `delta` > 0.
* Ensure basket upsell messages are not `None`

Also fix "is_anonymous" attribute value in WebTestCase subclass.
