Django 1.7.2 fixes several bugs in 1.7.1.

Additionally, Django's vendored version of six, `django.utils.six`, has been upgraded to the latest release (1.9.0).

## バグ修正

- Fixed a migration crash when adding an explicit `id` field to a model on SQLite (#23702).

- Prevented `flush` from loading initial data for migrated apps (#23699).

- Fixed a `makemessages` regression in 1.7.1 when `STATIC_ROOT` has the default `None` value (#23717).

- Added GeoDjango compatibility with mysqlclient database driver.

- Fixed MySQL 5.6+ crash with `GeometryField`s in migrations (#23719).

- Fixed a migration crash when removing a field that is referenced in `AlterIndexTogether` or `AlterUniqueTogether` (#23614).

- Updated the first day of the week in the Ukrainian locale to Monday.

- Added support for transactional spatial metadata initialization on SpatiaLite 4.1+ (#23152).

- Fixed a migration crash that prevented changing a nullable field with a default to non-nullable with the same default (#23738).

- Fixed a migration crash when adding `GeometryField`s with `blank=True` on PostGIS (#23731).

- Allowed usage of `DateTimeField()` as `Transform.output_field` (#23420).

- Fixed a migration serializing bug involving `float("nan")` and `float("inf")` (#23770).

- Fixed a regression where custom form fields having a `queryset` attribute but no `limit_choices_to` could not be used in a `ModelForm` (#23795).

- Fixed a custom field type validation error with MySQL backend when `db_type` returned `None` (#23761).

- Fixed a migration crash when a field is renamed that is part of an `index_together` (#23859).

- Fixed `squashmigrations` to respect the `--no-optimize` parameter (#23799).

- Made `RenameModel` reversible (#22248)

- Avoided unnecessary rollbacks of migrations from other apps when migrating backwards (#23410).

- Fixed a rare query error when using deeply nested subqueries (#23605).

- Fixed a crash in migrations when deleting a field that is part of a `index/unique_together` constraint (#23794).

- Fixed `django.core.files.File.__repr__()` when the file's `name` contains Unicode characters (#23888).

- Added missing context to the admin's `delete_selected` view that prevented custom site header, etc. from appearing (#23898).

- Fixed a regression with dynamically generated inlines and allowed field references in the admin (#23754).

- Fixed an infinite loop bug for certain cyclic migration dependencies, and made the error message for cyclic dependencies much more helpful.

- Added missing `index_together` handling for SQLite (#23880).

- Fixed a crash when `RunSQL` SQL content was collected by the schema editor, typically when using `sqlmigrate` (#23909).

- Fixed a regression in `contrib.admin` add/change views which caused some `ModelAdmin` methods to receive the incorrect `obj` value (#23934).

- Fixed `runserver` crash when socket error message contained Unicode characters (#23946).

- Fixed serialization of `type` when adding a `deconstruct()` method (#23950).

- Prevented the `django.contrib.auth.middleware.SessionAuthenticationMiddleware` from setting a `"Vary: Cookie"` header on all responses (#23939).

- Fixed a crash when adding `blank=True` to `TextField()` on MySQL (#23920).

- Fixed index creation by the migration infrastructure, particularly when dealing with PostgreSQL specific `{text|varchar}_pattern_ops` indexes (#23954).

- Fixed bug in `makemigrations` that created broken migration files when dealing with multiple table inheritance and inheriting from more than one model (#23956).

- Fixed a crash when a `MultiValueField` has invalid data (#23674).

- Fixed a crash in the admin when using "Save as new" and also deleting a related inline (#23857).

- Always converted `related_name` to text (Unicode), since that is required on Python 3 for interpolation. Removed conversion of `related_name` to text in migration deconstruction (#23455 and #23982).

- Enlarged the sizes of tablespaces which are created by default for testing on Oracle (the main tablespace was increased from 200M to 300M and the temporary tablespace from 100M to 150M). This was required to accommodate growth in Django's own test suite (#23969).

- Fixed `timesince` filter translations in Korean (#23989).

- Fixed the SQLite `SchemaEditor` to properly add defaults in the absence of a user specified `default`. For example, a `CharField` with `blank=True` didn't set existing rows to an empty string which resulted in a crash when adding the `NOT NULL` constraint (#23987).

- `makemigrations` no longer prompts for a default value when adding `TextField()` or `CharField()` without a `default` (#23405).

- Fixed a migration crash when adding `order_with_respect_to` to a table with existing rows (#23983).

- Restored the `pre_migrate` signal if all apps have migrations (#23975).

- Made admin system checks run for custom `AdminSite`s (#23497).

- Ensured the app registry is fully populated when unpickling models. When an external script (like a queueing infrastructure) reloads pickled models, it could crash with an `AppRegistryNotReady` exception (#24007).

- Added quoting to field indexes in the SQL generated by migrations to prevent a crash when the index name requires it (#24015).

- Added `datetime.time` support to migrations questioner (#23998).

- Fixed admindocs crash on apps installed as eggs (#23525).

- Changed migrations autodetector to generate an `AlterModelOptions` operation instead of `DeleteModel` and `CreateModel` operations when changing `Meta.managed`. This prevents data loss when changing `managed` from `False` to `True` and vice versa (#24037).

- Enabled the `sqlsequencereset` command on apps with migrations (#24054).

- Added tablespace SQL to apps with migrations (#24051).

- Corrected `contrib.sites` default site creation in a multiple database setup (#24000).

- Restored support for objects that aren't `str` or `bytes` in `django.utils.safestring.mark_for_escaping()` on Python 3.

- Supported strings escaped by third-party libraries with the `__html__` convention in the template engine (#23831).

- Prevented extraneous `DROP DEFAULT` SQL in migrations (#23581).

- Restored the ability to use more than five levels of subqueries (#23758).

- Fixed crash when `ValidationError` is initialized with a `ValidationError` that is initialized with a dictionary (#24008).

- Prevented a crash on apps without migrations when running `migrate --list` (#23366).
