* only one of partial_name or :as will be available as a local
  * `object` is removed
  * Simplify _layout_for in most cases.
    * Remove <% render :partial do |args| %>
    * <% render :partial do %> still works fine

Add destroyed? to ActiveRecord, include tests for polymorphic urls for destroyed objects and refactor mime responds tests and documentation.

  * Significantly simplifies setting and modifying cache control in other areas

Functional test runner finalizes response just like the integration test runner. In both runners, the @response object will now behave the same.

Some functional tests will need to be updated if they are relying on preprocessed data on the response.

Ported over the concept of public instance methods on controller child classes as callable action methods

  ActionView::Template is now completely independent from template
  storage, which allows different back ends such as the database.
  ActionView::Template's only responsibility is to take in the
  template source (passed in from ActionView::Path), compile it,
  and render it.

    Example: ActiveSupport::JSON.backend = "JSONGem"

  All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode().  Use of #to_json is not recommended, as it may clash with other libraries that overwrite it.  However, you can recover Rails specific functionality
  if you really want to use #to_json.

    gem 'json'
    ActiveSupport::JSON.backend = "JSONGem"

    class ActiveRecord::Base
      alias to_json rails_to_json
    end

Ensure expires_in without a :public key sets the Cache-Control header to private. [#2095 state:resolved]

This fixes a regression introduced in f2a32bd0, which wasn't exposed due to two
test methods having the same name.
