[ci skip] Getting to ready to merge into rails/rails

Add test cases for `#sanitize_sql_array` with named_bind_variables

This reverts commit 9712a7a1, reversing
changes made to 3e65c3d3.

Reverting because this caused test failures and while we have a followup
branch there is still one failure that happens randomly and isn't
straight forward to fix.

Controller generators should be creating IntegrationTest stubs instea…

Allows any Rake task to be run through `bin/rails` such as `bin/rails db:migrate`,
`bin/rails notes` etc.

The Rake tasks are appended to Rails' help output, and blend in as standard commands.

Prevent a 500 in the default controller scaffold

Update web-console to 3.0.0

The API isn't ready yet, which means we haven't documented it.

People can't make their own commands, so there's no reason to show it
in generated documentation.

If you update a record with no attributes, you'll hit a 500 from a guard
in `assign_attributes` raising:

```ruby
ArgumentError: When assigning attributes, you must pass a hash as an argument.
    app/controllers/users_controller.rb:44:in `block in update'
    app/controllers/users_controller.rb:43:in `update'
    test/controllers/users_controller_test.rb:37:in `block in <class:UsersControllerTest>'
```

Not a biggie, but may be quite confusing for the folks new to the
framework.

Fix paintIt method in JavaScript guides [ci skip]

See the rationale in the comment present in this patch.

Before this commit, the sole presence of the Listen constant
enabled the evented file watcher (unless listen resorted to
the polling backend).

This way, applications may depend on listen for other stuff
independently of this feature. Also, allows teams with mixed
setups to decide at boot time whether the evented watcher
should be enabled for each particular instance.

Web Console 3.0.0 is compatible with Rails 5, while the 2.x.x releases
aren't.

Tiny typo in the testing guide; articules should be articles.

Freshen up the client-side subscription examples. Fixes #118

add devise example to readme

Easy websocket url configuration

Allow regexp for a allowed_request_origins array

- Changed "paintIt" to "@paintIt" so that it can be called in an on
  click handler.
- Closes #22568

Use adapter supports_datetime_with_precision

So that it appears correctly in the CHANGELOG on github.

In Rails 5.1 `ActionController::TestCase` will be moved out of Rails
into it's own gem.

Please use `ActionDispatch::IntegrationTest` going foward.

Because this will be moved to a gem I used `# :stopdoc:` instead of
deleting the documentation. This will remove it from the Rails
documentation but still leave the method documented for when we move it
to a gem.

Guides have been updated to use the routing structure used in Integration
and all test examples have been updated to inherit from
`ActionDispatch::IntegrationTest` instead of `ActionController::TestCase.

Fixes #22496

Thanks to feedback from @ascrazy, @jeremy, and @javan
