Improves 049a3374aa85f33091f0e7cba8635edd4b4786bd:
* Attempt native `preventDefault()` before stepping in
* Fix that calling `preventDefault()` more than once would throw an error
* Fix that non-cancelable events could be canceled
Replaced the uses of `group.send(...)` in `option_groups_from_collection_for_select`
by calls to `value_for_collection(group, ...)`, allowing the use of
procs, lambdas and other callable objects as parameters.
`BigDecimal.new` has been deprecated in BigDecimal 1.3.3
which will be a default for Ruby 2.5.

```
cd rails
git grep -l BigDecimal.new | grep -v guides/source/5_0_release_notes.md | grep -v activesupport/test/xml_mini_test.rb | xargs sed -i -e "s/BigDecimal.new/BigDecimal/g"
```
- `activesupport/test/xml_mini_test.rb`
Editmanually to remove `.new` and `::`

This is a Rails 5.0 release notes.
This helper creates a link tag with preload keyword that allows to
browser to initiate early fetch of resources. Additionally this send
Early Hints if supported.

The def with blank `()` was newly added in #31176, but we have not used
the blank `()` style in most part of our code base.
So I've enabled `Style/DefWithParentheses` to prevent to newly added the
code.
When `form_with` was introduced we disabled the automatic
generation of ids that was enabled in `form_for`. This usually
is not an good idea since labels don't work when the input
doesn't have an id and it made harder to test with Capybara.
You can still disable the automatic generation of ids setting
`config.action_view.form_with_generates_ids` to `false.`
### Summary
The [`:field_error_proc`](https://github.com/rails/rails/blob/master/actionview/lib/action_view/base.rb#L145) is responsible for decorating input tags that refer to attributes with errors. This default build-in rails feature wrap invalid form elements with additional markup: `<div class="field_with_errors">[…]</div>`.
* Fix for `field_error_proc` wraps form select `optgroup`
* Fix for `field_error_proc` wraps form select divider `option`
* Add tests for uncovered elements with errors
[Fixes#31088]
#### Test coverage
* `test_select_grouped_options_with_errors`
* `test_time_zone_select_with_priority_zones_and_errors`
#### Extend test coverage
* `test_collection_select_with_errors`
* `test_label_with_errors`
* `test_check_box_with_errors`
* `test_check_boxes_with_errors`
* `test_radio_button_with_errors`
* `test_radio_buttons_with_errors`
* `test_collection_check_boxes_with_errors`
* `test_collection_radio_buttons_with_errors`
`Kernel.#spawn` execute command via the shell if contains shell
metacharacters in the command.
In that case, return value of `spawn` is pid of the shell, not the server.
Therefore, just killing the pid will leave the process of server.
In order to correctly kill the server, send a signal to the process
group, not the process.
Currently, the following error is shows only when run the test using
`bin/test`.
```
./bin/test -w test/template/log_subscriber_test.rb
Run options: --seed 17167
# Running:
/rails/actionview/test/template/log_subscriber_test.rb:34: warning: instance variable @defined_root not initialized
```
In `AVLogSubscriberTest`, if the `Rails.root` is not defined, define the
method and undef it in teardown.
https://github.com/rails/rails/blob/master/actionview/test/template/log_subscriber_test.rb#L21..L33
However, in `bin/test`, `Rails.root` is defined, which results in referring to
uninitialized variables and warnings.
Do a check if the 'rel' argument is passed in, and simply set it to
'nofollow' if 'rel' was not passed in. This prevents three string
allocations for each call to `link_to` in that scenario. In the scenario
where the 'rel' argument is passed in, performance is around the same as
before as the `key?` check is very fast.
