  Modified files:
    sys/sys              reboot.h 
    sys/boot/i386/boot2  boot2.c 
  Log:
  Changed the RB_PAUSE flag from 0x40000 to 0x100000 and marked the old
  value as reserved for internal use in boot blocks, because RB_PAUSE
  broke binary compatibility by usurping the RB_DUAL flag.  Probably no
  one except me has boot blocks for which this matters, since most boot
  blocks based on biosboot including pc98's boot2 can't boot elf kernels,
  and /boot/loader doesn't properly pass flags set by the previous stage.
  
  reboot.h:
  Also mark the historical RB_PROBEKBD flag (0x80000) as reserved for
  internal use in boot blocks.
  
  boot2.c:
  Added comments to inhibit usurping of other flags.
