Sync. with NetBSD:

- scsi prototypes.
- Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes,
  hacked a but.  Needs more work.
ss.c:
- Truncate to the window size in ssminphys(), not ssread().
- Missed some prototyping foo.
- Minor tweak; make sure window size is 0 on close.
- Change variable name to avoid GCC warning.
- Handle EOF a little differently.
