Amos Onn bd3c2900fc Fixed #25892 -- Optimized SeparateDatabaseAndState.database_backwards().
Now intermediate states in the database_backwards are cached, similar to
the executor's migrate() (or _migrate_all_backwards()). This makes the
migration run much faster (O(n) instead of O(n^2) over number of
database_operations).

Markus Holtermann e470f311d6 Fixed #24828 -- Allowed migration optimization across AlterFooTogether
The idea behind this change is, that AlterUniqueTogether,
AlterIndexTogether and AlterOrderWithRespectTo can always be moved after
an Add/Alter/Rename/RemoveField operation if they don't refer to the
respective field and are not empty sets / None.

Combined with the optimizations of duplicate AlterUniqueTogether,
AlterIndexTogether, and AlterOrderWithRespectTo operations from
128caa1e16, these operations are optimized
in a later round of the optimizer.

Thanks Tim Graham for the review.

Markus Holtermann 63f9b633f9 Fixed #24725 -- Allowed renaming of target models in ManyToMany relations
This is a regression caused by introducing rendered migration states in
1aa3e09c20 and the _meta refactoring in fb48eb0581.

Thanks to Danilo Bargen for reporting the issue and Marten Kenbeek and
Tim Graham for triaging the bug and providing the initial test case.

Matthew Wilkes e4b7daec11 Refs #24354 -- Prevented repointing of relations on superclasses when migrating a subclass's name change
The issue was hidden on 1.8+ until #24573 due to a bug inside the model
reloading process.

correct indentation.

Anssi Kääriäinen 8f30556329 Renamed Field.rel attribute to remote_field
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Loic Bistuer bed504d70b Fixed #24351, #24346 -- Changed the signature of allow_migrate().
The new signature enables better support for routing RunPython and
RunSQL operations, especially w.r.t. reusable and third-party apps.

This commit also takes advantage of the deprecation cycle for the old
signature to remove the backward incompatibility introduced in #22583;
RunPython and RunSQL won't call allow_migrate() when when the router
has the old signature.

Thanks Aymeric Augustin and Tim Graham for helping shape up the patch.

Carl Meyer bcb693ebd4 Revert "Fixed #23892 -- Made deconstructible classes forwards compatible"
This reverts commit f36151ed16.

Adding kwargs to deconstructed objects does not achieve useful
forward-compatibility in general, since additional arguments are silently
dropped rather than having their intended effect. In fact, it can make the
failure more difficult to diagnose. Thanks Shai Berger for discussion.

Patryk Zawadzki 21e21c7bc2 Fixed #23844 -- Used topological sort for migration operation dependency resolution.
This removes the concept of equality between operations to guarantee
compatilibity with Python 3.

Python 3 requires equality to result in identical object hashes. It's
impossible to implement a unique hash that preserves equality as
operations such as field creation depend on being able to accept
arbitrary dicts that cannot be hashed reliably.

Thanks Klaas van Schelven for the original patch in
13d613f800.
