2017-12-22[2.0.x] Fixed #28884 -- Fixed crash on SQLite when renaming a field in a ↵Simon Charette
model referenced by a ManyToManyField. Introspected database constraints instead of relying on _meta.related_objects to determine whether or not a table or a column is referenced on rename operations. This has the side effect of ignoring both db_constraint=False and virtual fields such as GenericRelation which aren't backend by database level constraints and thus shouldn't prevent the rename operations from being performed in a transaction. Regression in 095c1aaa898bed40568009db836aa8434f1b983d. Thanks Tim for the additional tests and edits, and Mariusz for the review. Backport of 9f7772e098439f9edea3d25ab127539fc514eeb2 from master
