Message:

Integrated JCTVC-O0092/0094/0096

1. Implement O1008 SHVC text pseudo code for direct/indirect reference layers detection
2. constraint on the maximum number of reference layers
3. constraint on the layer id of SPS/PPS
4. identify SPS rep format with index into the list of rep format in VPS
5. specify default direct dependency type in VPS
