SDL: Migrate to common host interface

Browse Source 
It now supports controllers again. But you have to bind them in Qt.

- Direct booting of homebrew executables
- Digital and analog controllers for input (rumble is forwarded to host)
- Qt and SDL frontends for desktop
- Qt frontend has graphical configuration, and controller binding
- Automatic content scanning - game titles/regions are provided by redump.org

**Currently, it is only possible to bind one input to each controller button/axis. Multiple bindings per button are planned for the future.**
## Default keyboard bindings for SDL frontend
Keyboard bindings in the SDL frontend are currently not customizable. For reference:
- **D-Pad:** W/A/S/D or Up/Left/Down/Right
- **Triangle/Square/Circle/Cross:** I/J/L/K or Numpad8/Numpad4/Numpad6/Numpad2
## Bindings for SDL frontend
Keyboard bindings in the SDL frontend are currently not customizable in the frontend itself. You should use the Qt frontend to set up your key/controller bindings first.
## Default bindings
Controller 1:
- **D-Pad:** W/A/S/D
- **Triangle/Square/Circle/Cross:** Numpad8/Numpad4/Numpad6/Numpad2
- **L1/R1:** Q/E
- **L2/L2:** 1/3
- **Start:** Enter
- **Select:** Backspace
Gamepads are automatically detected and supported. Tested with an Xbox One controller.
To access the menus with the controller, press the right stick down and use the D-Pad to navigate, A to select.
## Useful hotkeys for SDL frontend
- **F1-F8:** Quick load/save (hold shift to save)
- **F11:** Toggle fullscreen
Hotkeys:
- **Escape:** Power off console
- **ALT+ENTER:** Toggle fullscreen
- **Tab:** Temporarily disable speed limiter
- **Pause/Break:** Pause/resume emulation
- **Space:** Frame step
- **End:** Toggle software renderer
- **Page Up/Down:** Increase/decrease resolution scale in hardware renderers
- **End:** Toggle software renderer
## Tests
- Passes amidog's CPU and GTE tests in both interpreter and recompiler modes, partial passing of CPX tests
