  SVN rev 184322 on 2008-10-27 05:28:08Z by ed
  
  MFC r183565:
  
    Small cleanups to openpty().
  
    - Pass O_NOCTTY to posix_openpt(2). This makes the implementation work
      consistently on implementations that make the PTY the controlling TTY
      by default.
  
    - Call unlockpt() before opening the slave device. POSIX mentions that
      de slave device should only be opened after grantpt() and unlockpt()
      have been called.
  
    - Replace some redundant code by a label.
  
  As a safety net, add a call to revoke() to unlockpt(). All applications
  out there use openpty(), explicitly call revoke() or implement their own
  PTY allocation routines. Adding the call to unlockpt() won't hurt, but
  will prevent foot-shooting.
