"active_support/core_ext/module/aliasing" is no longer used since
#19434.

A regression in `deprecate_methods` was introduced in a982a42:

- Refactoring alias_chain to Module#prepend broke the possibility to deprecate class methods since the module
generated was prepended to the target's instance.
A suggestion to fix this was to use `AS#redefine_method` which would solve the
problem but with the cost of redefining directly the method.
Decided to go with the same alias_chain implementation as before instead.
- Fixes #33253

We don't need to have a special subscribe method for objects. The
regular `subscribe` method is more expensive than a specialized method,
but `subscribe` should not be called frequently. If that turns out to
be a hotspot, we can introduce a specialized method. :)

Fanout notifier can send event objects to subscribers now. Also moved
`end` lower in the `finish!` method to guarantee that CPU time is

* Use process clock instead of Time.now
This fixes any issues with the system clock changing and also eliminates
2 object allocations per event.
* Add start! and finish! methods to the event object so we can record
more information
* Adds cpu time, idle time, and allocation count for a particular event.

As discussed in #33203 rails command already looks for, and runs,
bin/rails if it is present.
We were mixing recommendations within guides and USAGE guidelines,
in some files we recommended using rails, in others bin/rails and
in some cases we even had both options mixed together.

- There was an issue inside controller tests where order params were not respected, the reason
was because we were calling `Hash#to_query` which sorts the results lexicographically.
1e4e1b62 fixed that issue by not using `to_query` but instead a utility function provided by rack.
- However with the fix came another issue where it's now no longer possible to do this
```
post :foo, params: { user: User.first }
# Prior to the patch the controller will receive { "user" => "1" }
# Whereas now you get { "user": "#<User: ...>" }
```
The fix in this PR is to modify `Hash#to_query` to sort only when it
doesn't contain an array structure that looks something like "bar[]"

Use class_eval or instance_eval when triggering lazy load hooks
|

- When lazy load hooks were triggered we were using
`Object.instance_eval` which evaluates the block in the context of
the class being passed. Most of the time that class was a
`Class`. If one wants to define a instance method on the class then
it wasn't possible.
```ruby
class A; end;
A.instance_eval do
def foo
puts 'bar'
end
end
A.new.foo #> NoMethodError: undefined method `foo`
A.foo #> bar
```
- This PR checks what object is passed when triggering the hooks and
either call `class_eval` or `instance_eval`. My rational and assumptions being
that if an instance of a class is passed, then the blocks needs to
evaluate in the context of that instance (i.e. defining a method
should only define it on that instance).
On the other hand, if a Class or Module is passed when triggering
hooks, then defining a method should define it on the class itself

Firstly, increment and decrement shouldn't care about the particulars of
key expiry. They should only know that they have to pass that responsibility
on to somewhere else.
Secondly, it moves the key normalization back inside the instrumentation like
it was originally. I think that matches the original design intention or at
the very least it lets users catch haywire key truncation.
Thirdly, it moves the changelog entry to the top of the file, where new entries
go. I couldn't understand what the entry was saying so I tried to rewrite it.

DeepCover revealed that most of these `wday != 0 ? wday - 1 : 6`
were not entirely covered, i.e. the case of `wday == 0` was not tested:
https://deep-cover.github.io/rails-cover/activesupport/activesupport/lib/active_support/core_ext/date_and_time/calculations.rb.html#L351
There's actually no valid reason to consider Sunday a special case,
so this commit simply reajusts the values used for calculations.

ruby/ruby@989e07c features switching `Range#===` to use internal `r_cover_p`
instead of rubyland `include?`. This breaks expected behavior of
`ActiveSupport::CoreExt::Range` documented since at least 8b67a02.
This patch adds overrides on `Range#cover?` and `Range#===` and places all
three in a single module, `CompareWithRange`.
*Requiring core_ext/range/include_range now causes a deprecation warnning*

In the app I'm working on I've wished that index_by had a buddy that would
assign the hash value instead of the key multiple times.
Enter index_with. Useful when building a hash from a static list of
symbols. Before you'd do:
```ruby
POST_ATTRIBUTES.map { |attr_name| [ attr_name, public_send(attr_name) ] }.to_h
```
But now that's a little clearer and faster with:
````ruby
POST_ATTRIBUTES.index_with { |attr_name| public_send(attr_name) }
```
It's also useful when you have an enumerable that should be converted to a hash,
but you don't want to muddle the code up with the overhead that it takes to create
that hash. So before, that's:
```ruby
WEEKDAYS.each_with_object(Hash.new) do |day, intervals|
intervals[day] = [ Interval.all_day ]
end
```
And now it's just:
```ruby
WEEKDAYS.index_with([ Interval.all_day ])
```
It's also nice to quickly get a hash with either nil, [], or {} as the value.

See #29632 for details. In short, it's possible to enter `LoadError#is_missing?` when `LoadError#path` returns `nil`, leading to `path.sub` throwing an none-to-helpful `NoMethodError`.
This tiniest of patch inserts `#to_s` before the `sub` call to make sure it succeeds. Affected surface area should be just as tiny since something has already gone wrong to get us into `#is_missing?` and the current behavior when `#path` returns `nil` seems clearly not intended.

- In #32472 I introduced a fix in order for all `after_teardown` method provided by libraries and Rails to run, even if the application's `teardown` method raised an error (That's the default minitest behavior). However this change wasn't enough and doesn't take in consideration the ancestors chain.
If a library's module containing an `after_teardown` method get included after the `SetupAndTeardown` module (one example is the [ActiveRecord::TestFixtures module](https://github.com/rails/rails/blob/7d2400ab61c8e3ed95e14d03ba3844e8ba2e36e4/activerecord/lib/active_record/fixtures.rb#L855-L856), then the ancestors of the test class would look something like
```ruby
class MyTest < ActiveSupport::TestCase
end
puts MyTest.ancestors # [MyTest, ActiveSupport::TestCase, ActiveRecord::TestFixtures, ActiveSupport::Testing::SetupAndTeardown]
```
Any class/module in the ancestors chain that are **before** the `ActiveSupport::Testing::SetupAndTeardown` will behave incorrectly:
- Their `before_setup` method will get called **after** all regular setup method
- Their `after_teardown` method won't even get called in case an exception is raised inside a regular's test `teardown`
A simple reproduction script of the problem here https://gist.github.com/Edouard-chin/70705542a59a8593f619b02e1c0a188c
- One solution to this problem is to have the `AS::SetupAndTeardown` module be the very first in the ancestors chain. By doing that we ensure that no `before_setup` / `after_teardown` get executed prior to running the teardown callbacks
