This commit contains the AudioCDManager changes from the gsoc2010-opengl branch. The other changes in that branch are restricted to the backends directory only (plus configure). The Nintendo DS and Dreamcast ports still need to be ported over to the new Audio CD system, but that should be fairly easy to do. svn-id: r54147
