  Modified:    sys/i386/isa sio.c
  Log:
  Several fixes to help "raw" tty mode work correctly with
  BREAK/parity/framing errors.
  Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
  1) Discard BREAK/parity at interrupt level when apropriate IGN*
  is set in iflag. It helps "raw" mode works even IGN* is set.
  2) Zero parity (if INPCK) and framing directly in buffer
  before passing it to b_to_q() in "raw" mode.
  Efficency:
  interrupt level: if no error occurse, only two "test" commands added
  "raw" mode: buf scan incc times for parity/framing added
