Log Message:
Update to nabud-1.3.  Upstream change log:

### nabud-1.3
* Support for the NHACP protocol version 0.1 draft.  Compatibility with
  the original ("0.0") NHACP is maintained.
* On Linux, Use termios2 to set the baud rate for serial connections, since
  that mechanism can support arbitrary baud rates, unlike the termios API in
  glibc.

### nabud-1.2.2
* Fixed an error in the GET-STATUS,TRANSMIT response that caused problems
  with the newer alternate NABU development ROMs.  Tip-of-the-hat to
  Nick Daniels for pointing it out.
