- Added lctl.c which is basically ptlctl/obdctl/debugctl all

  frankensteined together.  It should be possible to configure
  all of portals/lustre through it.
- network.c contains the portals bits
  device.c contains the device bits
  debug.c contains the debug bits
- Some functionality has been consolidated when it was redundant,
  there's still more of that to do!
- The thread handling that was in obdctl is broken for a little bit.
- All the original *ctl tools are uneffected.
- Several commands have been slightly renamed do to name collisions,
  for instance the obdctl list command is now device_list, so as
  not to conflict with debug_list or route_list.  It'll be pretty
  obvious.
