  Added files:
    sys/kern             tty_pts.c 
  Log:
  Bring in a sysv-style pts implementation, as found in the rwatson_pts perforce  branch. It works the same as its SysV/linux counterpart : You obtain a fd to    the master pseudo terminal by opening /dev/ptmx, which craetes a node for the   master as /dev/pty[num] and a node for the slave as /dev/pts/[num].
  It should play nicely with the existing BSD ptys.
  By default, the system will use the BSD ptys, one can set the sysctl
  kern.pts.enable to 1 to make it use the new pts system.
  The max number of pty that can be allocated on a system can be changed with the
  sysctl kern.pts.max. It defaults to 1000, and can be increased, but it is not
  recommanded, as any pty with a number > 999 won't be handled by whatever uses
  utmp(5).
