marius abfeec800f - In sunkbd_probe_keyboard() don't bother to determine the keyboard layout
as we have no use for that info. Instead let this function return the
  keyboard ID and verify at its invocation in sunkbd_configure() that we're
  talking to a Sun type 4/5/6 keyboard, i.e. a keyboard supported by this
  driver.
- Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective
  code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to
  emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by
  kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also
  triggers the use of AT keyboard maps and thus allows to use the map files
  in share/syscons/keymaps with this driver at the cost of an additional
  translation (in ukbd(4) this just is the way of operation).
- Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options
  of the other keyboard drivers allows to specify the default in-kernel
  keyboard map. For obvious reasons this made to only work when also using
  SUNKBD_EMULATE_ATKBD.
- Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(),
  which are also required for interoperability with kbdmux(4).
- Implement K_CODE mode and FreeBSD keypad compose.
- As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD
  case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than
  having to duplicate it and #ifdef some more code.
- Don't use the TX-buffer for writing the two command bytes for setting the
  keyboard LEDs as this consequently requires a hardware FIFO that is at
  least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't
  have. Thus use an inlined version of uart_putc() to consecutively write
  the command bytes (a cleaner approach would be to do this via the soft
  interrupt handler but that variant wouldn't work while in ddb(4)). [1]
- Fix some minor style(9) bugs.
