Introduce ActiveResource::Base.timeout. This allows a timeout to be set on the internal Net::HTTP instance ARes uses (default is 60 seconds). Setting a low timeout allows ARes clients to fail-fast in the event of a unresponsive/crashed server, rather than cause cascading failures in your application.

This reverts commit eef90029.

Reduce number of instance variables being copied from controller to
view. Instead, delegate them to controller instance.

Use the rails user when creating and dropping the database rather than falling back to the currently logged in user who may or may not have CREATE / DROP privileges and no password.

Closes #11564 (trac)

Duration #since and #ago with no argument (e.g., 5.days.ago) return TimeWithZone when config.time_zone is set. Introducing Time.current, which returns Time.zone.now if config.time_zone is set, otherwise just returns Time.now

Get rid of ActionController::Base#view_controller_internals flag and
use @@protected_view_variables for storing the list of controller
specific instance variables which should be inaccessible inside views.
