The logic allowing UniqueConstraint(fields).validate to preserve backward
compatiblity with Model.unique_error_message failed to account for cases where
the constraint might not be attached to a model which is a common pattern
during testing.
This changes allows for arbitrary UniqueConstraint(fields) to be tested in
isolation without requiring actual models backing them up.

Accessing generated field values on unsaved models caused a crash when
validating CheckConstraints and UniqueConstraints with expressions.

Sleep call leads to a hard to trace error in CI. Using an Event is
more deterministic, and should be less prone to environment
variations.

Generated fields have to be excluded from the INSERT query against the remade
table including the index.
Thanks Moshe Dicker for the report, David Sanders and Mariusz Felisiak for the
review.

Postgres >= 12.18, 13.14, 14.11, 15.6, 16.2 changed the way the immutability
of generated and default expressions is detected in postgres/postgres@743ddaf.
The adjusted test semantic is presereved by switching from __icontains to
__contains as both make use of a `%` literal which requires proper escaping.

A longer term solution is likely to have a better separation of parametrized
DDL altogether to handle checks, constraints, defaults, and generated fields
but such a change would require a significant refactor that isn't suitable
for a backport.
Thanks Adrian Garcia for the report.

Field.db_default accepts either literal Python values or compilables
(as_sql) and wrap the former ones in Value internally.
While 1e38f11 added support for automatic resolving of output fields for
types such as str, int, float, and other unambigous ones it's cannot do
so for all types such as dict or even contrib.postgres and contrib.gis
primitives.
When a literal, non-compilable, value is provided it likely make the
most sense to bind its output field to the field its attached to avoid
forcing the user to provide an explicit `Value(output_field)`.
Thanks David Sanders for the report.

MySQL doesn't allow literal DEFAULT values to be used for BLOB, TEXT,
GEOMETRY or JSON columns and requires expression to be used instead.

Prior to this work, when async tasks that process the request are cancelled due
to receiving an early "http.disconnect" ASGI message, the request_finished
signal was not being sent, potentially leading to resource leaks (such as
database connections).
This branch ensures that the request_finished signal is sent even in the case
of early termination of the response.

Regression in d9de74141e.
This is a long standing issue, however it caused a crash of
GeneratedFields for all output fields that have backend-specific
converters when the RETURNING clause is not supported
(MySQL and SQLite < 3.35).
That's why severity was exacerbated.

Depending on screen sizes, the selenium tests that would "click" or interact
with an element outside the scope of the visible window would produce test
failures (raising ElementNotInteractableException in CI runs).
This branch switches those to using ActionChains, which ensures that the click
(or other interaction) is performed only after successfully completing the
move to the relevant element.
