Add sdl_hints:add_callback/3 function
This also sets up esdl2 to start accepting callbacks.
The module/process esdl2_callbacks must always be running
for that purpose, so esdl2 was made an OTP application
instead of a simple library.
Implementation of the rest of SDL_hints will follow in
subsequent commits.
