From c537d5958e8b421ac4f9bef6c8b9e7425a6cf167 Mon Sep 17 00:00:00 2001
From: Michael Sevakis <jethead71@rockbox.org>
Date: Wed, 27 Apr 2011 03:08:23 +0000
Subject: Commit FS#12069 - Playback rework - first stages. Gives as thorough
 as possible a treatment of codec management, track change and metadata logic
 as possible while maintaining fairly narrow focus and not rewriting
 everything all at once. Please see the rockbox-dev mail archive on 2011-04-25
 (Playback engine rework) for a more thorough manifest of what was addressed.
 Plugins and codecs become incompatible.
