This reverts commit 8cbf8254.

This doesn't provide a way to turn off the escaping, but alternative template engine authors
can figure out what their default should be by calling this.  Avoids a messy version + plugin check.

This reverts commit 29b28066.

This reverts commit 610e94c0.

Avoid warning spam by flipping to the new callbacks mechanism.  These callbacks are actually never called by rails itself, merely there for plugins

Fixes RSpec integration example groups, which mixes its Matchers
module into ActiveSupport::TestCase.

Previously this example would always pass, even when cookies.delete was not called.

@request.cookies['foo'] = 'bar'
get :delete_cookie
assert_nil cookies['foo']

These rely on constant autoloads.

ActionView::Helpers::UrlHelper#url_for used to escape the URLs it generated by
default.  This was most commonly seen when generating a path with multiple
query parameters, e.g.

  url_for(:controller => :foo, :action => :bar, :this => 123, :that => 456)

would return

  http://example.com/foo/bar?that=456&this=123

escaping an ampersand that shouldn't be escaped.  This is both wrong and
inconsistent with the behavior of ActionController#url_for, and is changed.
