* Added B_TEAM_DEBUG_DEFAULT_FLAGS and B_THREAD_DEBUG_DEFAULT_FLAGS for

Browse Source 
convenience.
* Added/implemented callbacks for almost all missing debug events (team,
  thread, image creation/deletion, exceptions/faults, signals).
* The debugger can now specify how to deal with the event that stopped an
  event (ignore or handle signals, exceptions/faults).
* Implemented B_DEBUGGED_THREAD_GET_WHY_STOPPED debugger message.
* The cpu_state is now passed to the debugger with
  B_DEBUGGER_MESSAGE_THREAD_STOPPED notifications.
* Completed _user_debugger() implementation.
