sdl2: new package

From: Guillaume GARDET <[email protected]>

[Romain:
- Wrap Config.in help text at 72 columns.
- Move sdl2 package after sdl modules in Config.in. (Arnout)
- Explicitly disable dbus and wayland.
- Remove double underscore (SDL2__*).
- Unify autotools options to use --enable/--disable.
- Use x-includes and x-libraries to avoid path poisoning.
- Remove xlib_libXrender, xproto_inputproto and xproto_scrnsaverproto dependencies since the build system doesn't depend on them.
- Add Xlib_libXi, xlib_libScrnSaver and xlib_libXxf86vm dependencies.
- Handle autotools options (--enable/--disable) for each X11 dependencies.]
