English explanation to multi-level nested join

Raise AR::IrreversibleOrderError when #reverse_order can not do it's job

Added an "Or, in English..." explanation to the "Joining Nested Associations (Multiple Level)" example.

Update sucker_punch adapter's description

Remove nonsense definition of == from `AcceptItem`.  The definition only
compared names and not `q` values or even object identity.  The only use
was in the `assort!` method that really just wanted the index of the
item given the item's name.  Instead we just change the caller to use
`index` with the block form.

This commit refactors the private methods that were just aliases to []
to just directly use [] and cache the return values on the stack.

same strategy as `@text_xml_idx`: cache it on the stack to avoid ivar
lookups and the `||=` call.

this eliminates the ivar lookup and also eliminates the `||=`
conditional that happens every time we called the `text_xml_idx` method.

Update ActiveJob adapter for sucker_punch 2.0

Fix img alt attribute generation when using Sprockets >= 3.0

Fix typo in strong params hash deprecation message

and remove unecessary spaces in string interpolation.

The commit which originally added this behavior did not consider that
doing `Subclass.new` does not actually populate the `type` field in the
attributes (though perhaps it should). We simply need to not use the
defaults for STI related things unless we are instantiating the base
class.

Fixes #23285.

This PR includes two changes for 2.0.0:

- Breaking API change around `async.perform` --> `perform_async`
- New addition of `perform_in`, which now allows end users of the
  adapter to use the `enqueued_at` public API method.

Raises when #reverse_order can not process SQL order instead of making

We found that inserting all 600 schema_migrations for our mid-sized app takes about a minute on a cloud based CI environment.

I assume that the original code did not use multi-row-insert because SQLite3 was not supporting the syntax back then,
but it's been supported since 3.7.11: http://www.sqlite.org/releaselog/3_7_11.html

Fix undefined error for `ActionController::Parameters`

These tests were failing due to backwards incompatible changes, as apart
of the v1.0.3 release of rails-html-sanitizer.

The cache for `render file:` seems to also be used in the case of
`render(string)`.  If one is supposed to be a hit and the other is
supposed to be a miss, and they both reference the same file, then the
cache could return incorrect values.  This commit clears the cache
between runs so that we get non-cached behavior.
