I think it should return non-zero for 'file exists' and zero for
'doesn't exist or error'. The lazy programmer can just do
if (al_path_exists(f)) { X } else { Y };
and the diligent programmer can call al_get_errno() in the else part
to distinguish between 'no file' and 'error'.
This mirrors what stat itself does (though stat returns 0 for OK and
-1 for any error, which includes file not found)
