Get rid of relative_url_path in favor of respecting SCRIPT_NAME. Also added a way to specify a default SCRIPT_NAME when generating URLs out of the context of a request.

Deprecated ActionController::Base.session_options= and ActionController::Base.session_store= in favor of a config.session_store method (which takes params) and a config.cookie_secret variable, which is used in various secret scenarios. The old AC::Base options will continue to work with deprecation warnings.

Fix a bunch of failing AP / AM specs created from the previous AbstractController configuration refactor.

Deprecate IP spoofing settings that are directly on the controller in favor of configuring a middleware

  * ActionController::Base.ip_spoofing_check deprecated => config.action_dispatch.ip_spoofing_check
  * ActionController::Base.trusted_proxies deprecated => config.action_dispatch.trusted_proxies

Indicate that ActionController::Base.resource_action_separator is deprecated and only has an effect with the deprecated router DSL.

	* Refactored ActionPatch to use fullpath instead
