There are functions for both the extension string, and for checking individual 
extensions (eg. alcGetString(device, ALC_EXTENSIONS) / 
alGetString(AL_EXTENSIONS) return a GL-like list of extensions for ALC and AL 
respectively, and alcIsExtensionPresent(device, "foo") / 
alIsExtensionPresent("foo") says if extension 'foo' is supported).

However, I don't like the idea of white-listing extensions. IMO, it would be 
better to print a FIXME (as it currently does), and add any functions that get 
found. Often times it's just new enum tokens, and it would be silly to block 
them out because the thunk isn't aware of them.
