6<1> Fixed a conflict with ioctl usage. There were two different
7 functions using code #25. Made file formatting consistent.
8 Added two new ioctl codes: door closing and audio pitch playback.
9 Added a STEREO union called STEREO.

11
12<2> Added a new ioctl that allows you to find out what capabilities
13 a drive has and what commands it will accept. This allows a
14 user application to only offer controls (buttons, sliders, etc)
15 for functions that drive can actually do. Things it can't do
16 can disappear or be greyed-out (like some other system).
17 If the driver doesn't respond to this call, well, handle it the
18 way you used to do it.
