`find_in_batches` now returns an `Enumerator` when called without a block, so that it
can be chained with other `Enumerable` methods.

setup Bundler in engines `bin/rails` stub.

This is necessary when bundling gems locally using `BUNDLE_PATH`.
Without this patch `bin/rails` fails with:

Remove duplicate configuration option for ActiveSupport [ci skip]

psql implementation of #index_name_exists?
Remove missed usage of @first variable

With the introduction of `#second` method and friends, we added an
offsets hash which replaced the @first variable, so removing it from the
reset method to avoid creating an unused variable now.

Introduced in bc625080308e4853ae3036f2ad74fe3826e463ef.
Fail early with "Primary key not included in the custom select clause" in find_in_batches

Before this patch find_in_batches raises this error only on second iteration. So you will know about the problem only when you get the batch size threshold.

Extract all attribute changed work to its own method

This will make easier to hook on this feature to customize the behavior
Make enum feature work with dirty methods

To make this possible we have to override the save_changed_attribute
hook.
Add more tests for the dirty feature for enums
prepend table name for `Relation#select` columns.

This fixes a bug where `select(:id)` combined with `joins()` raised:

```
ActiveRecord::StatementInvalid: SQLite3::SQLException: ambiguous column name: id:
SELECT  id, authors.author_address_id
FROM "posts"
INNER JOIN "authors"
ON "authors"."id" = "posts"."author_id"
ORDER BY posts.id LIMIT 3
```

The `select_values` are still String and Symbols because other parts (mainly calculations.rb)
rely on that fact.

/cc @tenderlove
`has_one` and `belongs_to` accessors don't add ORDER BY to the queries anymore.

Since Rails 4.0, we add an ORDER BY in the `first` method to ensure consistent
results among different database engines. But for singular associations this
behavior is not needed since we will have one record to return. As this
ORDER BY option can lead some performance issues we are removing it for singular
associations accessors.

Fixes #12623.
