Simon Charette 9f7772e098 Fixed #28884 -- Fixed crash on SQLite when renaming a field in a 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 095c1aaa89.

Thanks Tim for the additional tests and edits, and Mariusz for the review.

Anssi Kääriäinen a18e43c5bb Made get_indexes() consistent across backends. 
Fixed #15933, #18082 -- the get_indexes() method introspection was
done inconsitently depending on the backend. For example SQLite
included all the columns in the table in the returned dictionary,
while MySQL introspected also multicolumn indexes.

All backends return now consistenly only single-column indexes.

Thanks to andi for the MySQL report, and ikelly for comments on
Oracle's get_indexes() changes.

Karen Tracey be87f0b0ec Fixed #3615: Added support for loading fixtures with forward references on database backends (such as MySQL/InnoDB) that do not support deferred constraint checking. Many thanks to jsdalton for coming up with a clever solution to this long-standing issue, and to jacob, ramiro, graham_king, and russellm for review/testing. (Apologies if I missed anyone else who helped here.)
