Sdl backend (#670)
* [audio] added sdl audio backend and in-tree atrac9 decoder * [input] replaced per-platform pad readers with sdl gamepad input * [video] added sdl window and host display plumbing * [gui] added host display options and per-game render settings * [bink] synced host movie playback to the guest audio clock * [cpu] hooked windows write faults into guest image tracking * [perf] added guest and render profiling, reserved host cpu lanes * [kernel] fixed stale pthread mutex handle alias * [host] wired the sdl session, save-data paths and project references * [audio] hoisted ajm trace stackalloc out of its loop * [video] Add guest image sync setting * [build] Strip native symbols * reuse
