  SVN rev 203001 on 2010-01-26 03:42:34Z by neel
  
  Create the "cfecons" tty directly using tty_makedev(). It is not clear what
  the intention of having two ttys pointing to the same cfe console device was.
  
  Also we were not initializing the output[] array passed in as input to
  tty_makedev() so one name of the ttys was garbage.
  
  Fix the code that calls cfe_write() to deal with the case where only a partial
  buffer is written out.
  
  cfe_cngetc() needs to return if there is no character available as input.
  If we don't do this then the cfe_timeout() function will spin forever
  because cfe_cngetc() will only ever return if there is valid input.
