This reverts commit 3be9134d.

Remove deprecated render_component. Please use the plugin from http://github.com/rails/render_component/tree/master

* Make the old deprecated relative_url_root still set the value as it's still used by mongrel
* Set the default from the ENV value when the file is required, not at runtime.

Simplified the logging format for parameters (don't include controller, action, and format as duplicates) [DHH]

Let fresh_when actually do the head(:not_modified). Cleaner and we get the filter halting for free then.

Added stale?/fresh? and fresh_when methods to provide a layer of abstraction above request.fresh? and friends [DHH]

Return processing lock to dispatcher, the finer grained lock was incompatible with the reloading in development mode.

This commit also adds ActionController::Dispatcher#dispatch_unlocking -- non-locking version of dispatch.
It's named anologously to POSIX {getc,getchar,...}_unlocked functions.
