You can get it with gfx_driver->id currently.

I think, we should just add a function like this:

AL_DRIVER_INFO *al_get_driver_info(driver), where driver can be:

AL_SYSTEM_DRIVER
AL_GFX_DRIVER
AL_DIGI_DRIVER
AL_JOYSTICK_DRIVER
AL_TIMER_DRIVER
AL_MIDI_DRIVER
and so on..

And struct AL_DRIVER_INFO
{
    AL_ID id;
    char const *name;
    char const *description;
    possibly more info?
}

That way, we need no separate is_gfx_driver_installed and
get_gfx_driver_id functions, which, when done for all drivers, would
clutter the API quite a bit.
