- split up detect.cpp into snd, cpu, gfx (headers were already split) - rename detect functions for more clarity (e.g. get_cur_vmode -> gfx_get_video_mode) - rename lib/res/sound/snd to snd_mgr to avoid conflict with sysdep/snd.cpp - waio: set errno in aio_rw (addresses bug #73) This was SVN commit r3745.
