This commit restores the ability to assign cookies for testing via
@request.env['HTTP_COOKIE'] and @request.cookies, e.g:

    @request.env['HTTP_COOKIE'] = 'user_name=david'
    get :index
    assert_equal 'david', cookies[:user_name]

and

    @request.cookies[:user_name] = 'david'
    get :index
    assert_equal 'david', cookies[:user_name]

Assigning via cookies[] is the preferred method and will take precedence
over the other two methods. This is so that cookies set in controller
actions have precedence and are carried over between calls to get, post, etc.

Assigning cookies for test cases should now use cookies[], e.g:

  cookies[:email] = 'user@example.com'
  get :index
  assert_equal 'user@example.com', cookies[:email]

To clear the cookies, use clear, e.g:

  cookies.clear
  get :index
  assert_nil cookies[:email]

We now no longer write out HTTP_COOKIE and the cookie jar is
persistent between requests so if you need to manipulate the environment
for your test you need to do it before the cookie jar is created.

Replace references to ActiveSupport::SecureRandom with just SecureRandom, and require 'securerandom' from the stdlib when active support is required.

- exclude Rack::Test::UploadedFile to pass existing tests. Are there any
  other types we're missing?

This reduces false positives that come from using ints in params in
tests, which do not get converted to strings in the tests. In
implementations going through rack, they do get converted to strings.

- David Chelimsky and Sam Umbach

since ActionDispatch::Http::Parameters#encode_params will force encoding on all params strings (when using an encoding aware Ruby), dup all strings passed into process.  This prevents modification of params passed in and, more importantly, doesn't barf when a frozen string is passed
thanks and high fives to kinsteronline

- cookies can be set using string or symbol keys
- cookies are preserved across calls to get, post, etc.
- cookie names and values are escaped
- cookies can be cleared using @request.cookies.clear

This removes all deprecated classes in ActionController related to
Routing, Abstract Request/Response and Integration/IntegrationTest.
All tests and docs were changed to ActionDispatch instead of ActionController.

More work still needs to be done on some of these names
(render_template.action_view and render_template!.action_view particularly)
but this allows (for example) /^sql/ to subscribe to all
the various ORMs without further modification

- this makes it possible for other test frameworks
  to hook into testing facilities provided by Rails
  without having to subclass AC::TestCase.
