Create a deprecation behavior that triggers a notification for deprecation notices, and make the behaviors independent of the environment names.

* In Rails 2.3 apps being upgraded, you will need to add the deprecation
  configuration to each of your environments. Failing to do so will
  result in the same behavior as Rails 2.3, but with an outputted warning
  to provide information on how to set up the setting.
* New Rails 3 applications generate the setting
* The notification style will send deprecation notices using
  ActiveSupport::Notifications. Third-party tools can listen in to
  these notifications to provide a streamlined view of the
  deprecation notices occurring in your app.
* The payload in the notification is the deprecation warning itself
  as well as the callstack from the point that triggered the
  notification.

No need to check if the attribute exists (this is the same behavior as in 2.3) [#4994 state:resolved] and [#5003 state:resolved]

Add scoping and unscoped as the syntax to replace the old with_scope and with_exclusive_scope. A few examples:

* with_scope now should be scoping:

Before:

  Comment.with_scope(:find => { :conditions => { :post_id => 1 } }) do
    Comment.first #=> SELECT * FROM comments WHERE post_id = 1
  end

After:

  Comment.where(:post_id => 1).scoping do
    Comment.first #=> SELECT * FROM comments WHERE post_id = 1
  end

* with_exclusive_scope now should be unscoped:

  class Post < ActiveRecord::Base
    default_scope :published => true
  end

  Post.all #=> SELECT * FROM posts WHERE published = true

Before:

  Post.with_exclusive_scope do
    Post.all #=> SELECT * FROM posts
  end

After:

  Post.unscoped do
    Post.all #=> SELECT * FROM posts
  end

Notice you can also use unscoped without a block and it will return an anonymous scope with default_scope values:

  Post.unscoped.all #=> SELECT * FROM posts

This reverts commit 2c4f8aae.

with_exclusive_scope does not work properly if ARel is passed. It does work nicely if hash is passed. Blow up if user is attempting it pass ARel to with_exclusive_scope.

HTML specifications recommend the escaping of urls in web pages,
which url_for does by default for string urls and consquently
urls generated by path helpers as these return strings.

Hashes passed to url_for are not escaped by default and this
commit reverses this default so that they are escaped.

Deprecate the old router DSL. Since it is still used intensively across ActionPack test suite, patches that translates Rails internal tests to the new router DSL are welcome (note though that a few tests shouldn't be translated since they are testing exactly the old mapper API, like the ones in actionpack/test/controller/resource_test.rb and actionpack/test/controller/routing_test.rb)
