module_param: avoid bool abuse, add bint for special cases.
For historical reasons, we allow module_param(bool) to take an int (or an unsigned int). That's going away. A few drivers really want an int: they set it to -1 and a parameter will set it to 0 or 1. This sucks: reading them from sysfs will give 'Y' for both -1 and 1, but if we change it to an int, then the users might be broken (if they did "param" instead of "param=1"). Use a new 'bint' parser for them. (ntfs has a different problem: it needs an int for debug_msgs because it's also exposed via sysctl.)
