From 12375d1d3aa41f7d277a9af584c7b810b636ec95 Mon Sep 17 00:00:00 2001
From: Michael Sevakis <jethead71@rockbox.org>
Date: Wed, 2 Mar 2011 08:49:38 +0000
Subject: Merge functionality of wakeups and semaphores-- fewer APIs and object
 types. semaphore_wait takes a timeout now so codecs and plugins have to be
 made incompatible. Don't make semaphores for targets not using them.
