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).

Simon Charette c4e372aaf4 Fixed #25852 -- Made sure AlterModelManager forces a reload of its model state.

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.

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.
