I fixed kdump to find at least the system ioctls that it attempts to support.
It still doesn't know about machine-dependent ioctls.  Perhaps there should
be a <machine/ioctl.h> that includes all machine-dependent ioctl files.

rlogin still uses the crufty tty compatibility ioctls.  I thought that
getty was the last application that used them.  Anyway, rlogin switches
to non-canonical mode by swiching to RAW mode.  The compatibility
interface doesn't meddle with MIN/TIME (there would be no way to restore
them) so MIN=0 gives not-very-RAW mode.
