d3a935f01f Refs #27768 -- Reversed order of optimized and in-between operations. 
Operations can only be optimized through if they don't reference any of the
state the operation they are compared against defines or alters, so it's
safe to reverse the order.

for squashed migrations.

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.

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.

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.

956bd64424 Fixed #22397 -- Issues removing M2M field with explicit through model 
Changed the migration autodetector to remove models last so that FK

in the migration state renderer to error out in the presence of
dangling references instead of leaving them as strings. Fixed a bug

"through" models properly (i.e., do nothing successfully).
