Andrew White d017e92e1d Use a custom route vistor for optimized route generation
Using a Regexp to replace dynamic segments in a path string is fraught
with difficulty and can lead to odd edge cases like #13349. Since we
already have a parsed representation of the path it makes sense to use
that to generate an array of segments that can be used to build an
optimized route's path quickly.

Tests on a simple route (e.g. /posts/:id) show a speedup of 35%:

    New Helper:        153464.5 (±4.9%) i/s -     772800 in   5.047834s

Tests on a more complex route show even an greater performance boost:

    New Helper:         78815.5 (±4.1%) i/s -     398268 in   5.062161s

It also has the added benefit of fixing the edge cases described above.

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
