Django 1.10.1 risolve alcuni bug in 1.10.

## Correzioni di bug

- Fixed a crash in MySQL connections where `SELECT @@SQL_AUTO_IS_NULL` doesn’t return a result (#26991).

- Allowed `User.is_authenticated` and `User.is_anonymous` properties to be compared using `==`, `!=`, and `|` (#26988, #27154).

- Removed the broken `BaseCommand.usage()` method which was for `optparse` support (#27000).

- Fixed a checks framework crash with an empty `Meta.default_permissions` (#26997).

- Fixed a regression in the number of queries when using `RadioSelect` with a `ModelChoiceField` form field (#27001).

- Fixed a crash if `request.META['CONTENT_LENGTH']` is an empty string (#27005).

- Fixed the `isnull` lookup on a `ForeignKey` with its `to_field` pointing to a `CharField` or pointing to a `CharField` defined with `primary_key=True` (#26983).

- Prevented the `migrate` command from raising `InconsistentMigrationHistory` in the presence of unapplied squashed migrations (#27004).

- Fixed a regression in `Client.force_login()` which required specifying a `backend` rather than automatically using the first one if multiple backends are configured (#27027).

- Made `QuerySet.bulk_create()` properly initialize model instances on backends, such as PostgreSQL, that support returning the IDs of the created records so that many-to-many relationships can be used on the new objects (#27026).

- Fixed crash of `django.views.static.serve()` with `show_indexes` enabled (#26973).

- Fixed `ClearableFileInput` to avoid the `required` HTML attribute when initial data exists (#27037).

- Fixed annotations with database functions when combined with lookups on PostGIS (#27014).

- Reallowed the `{% for %}` tag to unpack any iterable (#27058).

- Made `makemigrations` skip inconsistent history checks on non-default databases if database routers aren’t in use or if no apps can be migrated to the database (#27054, #27110, #27142).

- Removed duplicated managers in `Model._meta.managers` (#27073).

- Fixed `contrib.admindocs` crash when a view is in a class, such as some of the admin views (#27018).

- Reverted a few admin checks that checked `field.many_to_many` back to `isinstance(field, models.ManyToManyField)` since it turned out the checks weren’t suitable to be generalized like that (#26998).

- Added the database alias to the `InconsistentMigrationHistory` message raised by `makemigrations` and `migrate` (#27089).

- Fixed the creation of `ContentType` and `Permission` objects for models of applications without migrations when calling the `migrate` command with no migrations to apply (#27044).

- Included the already applied migration state changes in the `Apps` instance provided to the `pre_migrate` signal receivers to allow `ContentType` renaming to be performed on model rename (#27100).

- Reallowed subclassing `UserCreationForm` without `USERNAME_FIELD` in `Meta.fields` (#27111).

- Fixed a regression in model forms where model fields with a `default` that didn’t appear in POST data no longer used the `default` (#27039).
