Small changes to Gemfile.lock and CHANGELOG

Update Gemfile.lock

Given that this pull request affects a mutable value, we need to test
for and document the affects on the receiver in this case.

Additionally, this pull request was missing a CHANGELOG entry.

Move from `AS::Callbacks::CallbackChain.halt_and_display_warning_on_return_false`
to `AS::Callbacks.halt_and_display_warning_on_return_false` base on
[this
discussion](https://github.com/rails/rails/pull/21218#discussion_r39354580)

Fix the documentation broken by 0a120a81

With this we can perform new assertions on the returned value without having
to cache it with an outer variable or wrapping all subsequent assertions inside
the `assert_difference` block.

Before:

```
post = nil
assert_difference -> { Post.count }, 1 do
  Post.create
end

assert_predicate post, :persisted?
```

Now:

```
post = assert_difference -> { Post.count } do
  Post.create
end

assert_predicate post, :persisted?
```

Rails 4.2.3 AS::Callbacks will not halt chain if `false` is returned.
That is the behavior of specific callbacks like AR::Callbacks and
AM::Callbacks.

The concept of a blank date or time doesn't make sense so we can short
circuit the calls for `blank?` on these classes to gain small speed boost.

Fixes #21657

The thread_safe gem is being deprecated and all its code has been merged
into the concurrent-ruby gem. The new class, Concurrent::Map, is exactly
the same as its predecessor except for fixes to two bugs discovered
during the merge.

The problem existed where if your ArrayInquirer values were
strings but you checked them using any? with a symbol, it would
not find the value. Now it will correctly check whether both
the String form or the Symbol form are included in the Array.

- Extracted `DELIMITED_REGEX` to `delimited_regex` method and made use of  user passed `options[:delimited_regex]` if available. Changed `DELIMITED_REGEX` to `DEFAULT)DELIMITED_REGEX` to signify what it means.
- Added tests for number to delimited and number to currency in both actionview and activesupport.

Fix #20869

Before:

```ruby
  twz = DateTime.now.in_time_zone
  twz.eql?(twz.dup) => false
```

Now:

```ruby
  twz = DateTime.now.in_time_zone
  twz.eql?(twz.dup) => true
```

Please notice that this fix the `TimeWithZone` comparison to itself,
not to `DateTime`. Based on #3725, `DateTime` should not be equal to
`TimeWithZone`.

ActiveSupport::HashWithIndifferentAccess select and reject should return enumerator if called without block

The concurrent-ruby gem is a toolset containing many concurrency
utilities. Many of these utilities include runtime-specific
optimizations when possible. Rather than clutter the Rails codebase with
concurrency utilities separate from the core task, such tools can be
superseded by similar tools in the more specialized gem. This commit
replaces `ActiveSupport::Concurrency::Latch` with
`Concurrent::CountDownLatch`, which is functionally equivalent.

Use `ActiveSupport::Multibyte::Unicode.tidy_bytes` to handle invalid UTF-8
strings in `ERB::Util.unwrapped_html_escape` and `ERB::Util.html_escape_once`.
Prevents user-entered input passed from a querystring into a form field from
causing invalid byte sequence errors.

:nail: remove extraneous bracket

Passing 999999000 < `:nsec` < 999999999 and 999999 < `:usec` < 1000000
to change a time with utc_offset doesn't throw an `ArgumentError`.

Allows fetching the same values from arrays as from ActiveRecord associations.

`Delegator` inherits from `BasicObject`, which means that it will not
have `Object#try` defined. It will then delegate the call to the
underlying object, which will not (necessarily) respond to the method
defined in the enclosing `Delegator`.

This patches `Delegator` with the `#try` method to work around the
surprising behaviour.

Fixes #5790

By this way Integer, Rational, Float, Fixnum, Bignum classes have the same behaviour

Previously when converting AS::TimeWithZone to YAML it would be output
as a UTC timestamp. Whilst this preserves the time information accurately
it loses the timezone information. This commit changes that so that it is
saved along with the time information. It also provides nicer encoding of
AS::TimeZone instances themselves which previously embedded all of the
data from the TZInfo records.

Fixes #9183.
