Description Bernd Hufmann CLA 2011-08-30 11:22:03 EDT 
The Kernel State System is not initialized when selecting a new trace/experiment. 

This is only visible when two views are open which rely on the kernel state system (e.g. Statistics View and Resource View).
 
This was originally noticed when opening a specific trace and the cumulative time and elapsed time were negative. 

To reproduce:
- Import attached trace to workspace 
- Open LTTng statistics view and resource view
- Open above trace

The Statistics view will show a negative cumulative and elapsed time.

Fix for state initialization bug

When streaming was introduced, the experiment time range value TmfTimeRange.NULL was defined for special handlings. This range is not handled correctly, when a state checkpoint is restored or at startup when the state needs to be initialized.

This patch fixes the bug.
