  Modified files:
    sys/i386/isa         syscons.c syscons.h 
  Log:
  Add a new compile option SC_HISTORY_SIZE to specify the history buffer
  size in terms of lines (instead of bytes).  When changing video mode
  in ioctl SW_XXX commands, syscons checks scp->history_size and
  allocate a history buffer at least as large as the new screen size.
  (This was unnecessary before, because HISTORY_SIZE was as large as 100
  lines and this is bigger than the maximum screen size: 60 lines).
  Similar adjustment is done in ioctl CONS_HISTORY command too.
