  Log:
  - Split ioctl() up into ioctl() and kern_ioctl().  The kern_ioctl() assumes
    that the 'data' pointer is already setup to point to a valid KVM buffer
    or contains the copied-in data from userland as appropriate (ioctl(2)
    still does this).  kern_ioctl() takes care of looking up a file pointer,
    implementing FIONCLEX and FIOCLEX, and calling fi_ioctl().
  - Use kern_ioctl() to implement xenix_rdchk() instead of using the stackgap
    and mark xenix_rdchk() MPSAFE.
