Django 3.2.1 fixes a security issue and several bugs in 3.2.

## CVE-2021-31542: Potential directory-traversal via uploaded files

`MultiPartParser`, `UploadedFile`, and `FieldFile` allowed directory-traversal via uploaded files with suitably crafted file names.

In order to mitigate this risk, stricter basename and path sanitation is now applied.

## Perbaikan kesalahan

- Corrected detection of GDAL 3.2 on Windows (#32544).

- Fixed a bug in Django 3.2 where subclasses of `BigAutoField` and `SmallAutoField` were not allowed for the `DEFAULT_AUTO_FIELD` setting (#32620).

- Fixed a regression in Django 3.2 that caused a crash of `QuerySet.values()/values_list()` after `QuerySet.union()`, `intersection()`, and `difference()` when it was ordered by an unannotated field (#32627).

- Restored, following a regression in Django 3.2, displaying an exception message on the technical 404 debug page (#32637).

- Fixed a bug in Django 3.2 where a system check would crash on a reverse one-to-one relationships in `CheckConstraint.check` or `UniqueConstraint.condition` (#32635).

- Fixed a regression in Django 3.2 that caused a crash of `ModelAdmin.search_fields` when searching against phrases with unbalanced quotes (#32649).

- Fixed a bug in Django 3.2 where variable lookup errors were logged rendering the sitemap template if alternates were not defined (#32648).

- Fixed a regression in Django 3.2 that caused a crash when combining `Q()` objects which contains boolean expressions (#32548).

- Fixed a regression in Django 3.2 that caused a crash of `QuerySet.update()` on a queryset ordered by inherited or joined fields on MySQL and MariaDB (#32645).

- Fixed a regression in Django 3.2 that caused a crash when decoding a cookie value, used by `django.contrib.messages.storage.cookie.CookieStorage`, in the pre-Django 3.2 format (#32643).

- Fixed a regression in Django 3.2 that stopped the shift-key modifier selecting multiple rows in the admin changelist (#32647).

- Fixed a bug in Django 3.2 where a system check would crash on the `STATICFILES_DIRS` setting with a list of 2-tuples of `(prefix, path)` (#32665).

- Fixed a long standing bug involving queryset bitwise combination when used with subqueries that began manifesting in Django 3.2, due to a separate fix using `Exists` to `exclude()` multi-valued relationships (#32650).

- Fixed a bug in Django 3.2 where variable lookup errors were logged when rendering some admin templates (#32681).

- Fixed a bug in Django 3.2 where an admin changelist would crash when deleting objects filtered against multi-valued relationships (#32682). The admin changelist now uses `Exists()` instead of `QuerySet.distinct()` because calling `delete()` after `distinct()` is not allowed in Django 3.2 to address a data loss possibility.

- Fixed a regression in Django 3.2 where the calling process environment would not be passed to the `dbshell` command on PostgreSQL (#32687).

- Fixed a performance regression in Django 3.2 when building complex filters with subqueries (#32632). As a side-effect the private API to check `django.db.sql.query.Query` equality is removed.
