From 2054627caa7f71c564ce35b4525b6281fcd2cc39 Mon Sep 17 00:00:00 2001
From: Michael Sevakis <jethead71@rockbox.org>

Subject: Have the codec thread do callbacks instead of messing with the stack
 which is much simpler and safer. Remove threads array from plugin API since
 it now serves no purpose. Up minimum API version and sort.
