Because the glsl front-end uses Ruamoko to compile its builtins, it needs to switch languages, and the cleanest way to do so is to use a context object that gets passed around. This removes not only the current_language global, but also (as a bonus) any real references to flex's scanner object (there's still a pointer in rua_ctx_t, but it's no longer a parameter (which caused some pain in the change)).
