perform the required repointing.

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.

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.

bcb693ebd4 Revert "Fixed #23892 -- Made deconstructible classes forwards compatible" 
This reverts commit f36151ed169813f2873e13ca9de616cfa4095321.

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.

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
13d613f80011852404198dfafd1f09c0c0ea42e6.
