31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

well as an 8 port isa card from riscom.  sio16 (sbus) frontend coming
shortly.

this is heavily based on the com and zs drivers.
