Add atomic_t<>::try_dec instead of fetch_dec_sat Add atomic_t<>::try_inc GDBDebugServer is broken (needs rewrite) Removed old_thread class (former named_thread) Removed storing/rethrowing exceptions from thread Emu.Stop doesn't inject an exception anymore task_stack helper class removed thread_base simplified (no shared_from_this) thread_ctrl::spawn simplified (creates detached thread) Implemented overrideable thread detaching logic Disabled cellAdec, cellDmux, cellFsAio SPUThread renamed to spu_thread RawSPUThread removed, spu_thread used instead Disabled deriving from ppu_thread Partial support for thread renaming lv2_timer... simplified, screw it idm/fxm: butchered support for on_stop/on_init vm: improved allocation structure (added size)
