Backport of c071c408d72330b422c124a6bdd85a68acae9566 from master
The namespace of the constraint must be included when making the
constraint immediate.

Thanks Rodrigo Estevao for the report.

This allows adding foreign key constraints inline and changing data in
the same migration on PostgreSQL 10+.
Regression in 738faf9da2a5cd03148a36375db80746c99c9623.
Thanks Janne Rönkkö for the report and Simon Charette for the
implementation idea and review.
* assertIsNone()/assertIsNotNone() instead of comparing to None.
* assertLess() for < comparisons.
* assertIs() for 'is' expressions.
* assertIsInstance() for isinstance() expressions.
* rounding of assertAlmostEqual() for round() expressions.
* assertIs(..., True/False) instead of comparing to True/False.
* assertIs()/assertIsNot() for ==/!= comparisons.
* assertNotEqual() for == comparisons.
* assertTrue()/assertFalse() instead of comparing to True/False.
Mixing local test models with non-local models resulted in a referential
integrity error during tear down since the models are removed in separate
schema editor instances which each check constraints.
Failure appeared after 7289874adceec46b5367ec3157cdd10c711253a0.
Removed DatabaseIntrospection.table_name_converter()/column_name_converter()
and use instead DatabaseIntrospection.identifier_converter().
Removed DatabaseFeatures.uppercases_column_names.
Thanks Tim Graham for the initial patch and review and Simon Charette
for the review.
Added a test for constraint names in the database.
Updated SQLite introspection to use sqlparse to allow reading the
constraint name for table check and unique constraints.

Stopped dropping and recreating foreign key constraints on other fields
in the same table as the one which is actually being altered in an
AlterField operation.
Regression in c3e0adcad8d8ba94b33cabd137056166ed36dae0.
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.
