This reverts commit 3ea840355409dc205a9e0d027fc09f1452636969, reversing

activerecord/lib/active_record/relation/query_methods.rb
Reason: using `from` without `select` should not change the select list
to SELECT * because it can lead different query results. If it is needed
to change the table to a subquery or a view you can pass a table alias
in the `from` call or use `select('subquery.*')`.
Fixes #14049.

Since its conception arel was made to be private API of Active Record.
If users want to use arel features directly we should provide a way
using the Active Record API without exposing the arel implementation.

There is no gain in `referencing` tables that are not used for preloading.
Furthermore it will break if polymorphic associations are invloved. This
is because `references_eager_loaded_tables?` uses all `reference_values`
to decide wether to `eager_load` or `preload`.

This commit fixes two regressions introduced in cafe31a078 where
newly created finder methods #second, #third, #forth, and #fifth
caused a NoMethodError error on reload associations and where we
were pulling the wrong element out of cached associations.
Examples:
some_book.authors.reload.second
# Before
# => NoMethodError: undefined method 'first' for nil:NilClass
# After
# => #<Author id: 2, name: "Sally Second", ...>
some_book.first.authors.first
some_book.first.authors.second
# Before
# => #<Author id: 1, name: "Freddy First", ...>
# => #<Author id: 1, name: "Freddy First", ...>
# After
# => #<Author id: 1, name: "Freddy First", ...>
# => #<Author id: 2, name: "Sally Second", ...>
Fixes #13783.

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.

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.

This commit bring the famous ordinal Array instance methods defined
in ActiveSupport into ActiveRecord as fully-fledged finders.
These finders ensure a default ascending order of the table's primary
key, and utilize the OFFSET SQL verb to locate the user's desired
record. If an offset is defined in the query, calling #second adds
to the offset to get the actual desired record.
Fixes #13743.

This change was necessary because the whitelist wouldn't work.
It would be painful for users trying to update their applications.
This blacklist intent to prevent odd bugs and confusion in code that call mutator
methods directely on the `Relation`.

Using the name of an association in `where` previously worked only
if the value was a single `ActiveRecrd::Base` object. e.g.
Post.where(author: Author.first)
Any other values, including `nil`, would cause invalid SQL to be
generated. This change supports arguments in the `where` query
conditions where the key is a `belongs_to` association name and the
value is `nil`, an `Array` of `ActiveRecord::Base` objects, or an
`ActiveRecord::Relation` object.
# Given the Post model
class Post < ActiveRecord::Base
belongs_to :author
end
# nil value finds records where the association is not set
Post.where(author: nil)
# SELECT "posts".* FROM "posts" WHERE "posts"."author_id" IS NULL
# Array values find records where the association foreign key
# matches the ids of the passed ActiveRecord models, resulting
# in the same query as Post.where(author_id: [1,2])
authors_array = [Author.find(1), Author.find(2)]
Post.where(author: authors_array)
# ActiveRecord::Relation values find records using the same
# query as Post.where(author_id: Author.where(last_name: "Emde"))
Post.where(author: Author.where(last_name: "Emde"))
Polymorphic `belongs_to` associations will continue to be handled
appropriately, with the polymorphic `association_type` field added
to the query to match the base class of the value. This feature
previously only worked when the value was a single `ActveRecord::Base`.
class Post < ActiveRecord::Base
belongs_to :author, polymorphic: true
end
Post.where(author: Author.where(last_name: "Emde"))
# Generates a query similar to:
Post.where(author_id: Author.where(last_name: "Emde"), author_type: "Author")
