Implementation of client_state NBO operations.

Browse Source 
- Implemented calls to enter and leave NBO phase one and two
- Extended client_state mode checking to include m_nbo
- Changed client_state state and mode change sanity checks to
  print a warning and assert() instead of throwing exceptions
  to be more graceful in release builds.
