This reverts commit 1a33f26e.

includes:
- rename flag HandleCraAsBlaFlag to HandleCraAsCvsStartFlag
- changes of NAL unit types (reduced number)
- profile_tier_level and general_constraint_info structures

Relying on dead function

advantages:
- no re-definition of NAL unit type (which are going to change)
disadvantages:
- dependency on CommonLib

Note: Further updates will require that the version of parcat matches the software version (VTM/JEM/HM). Thus a version printout was added.

- remove duplicate ALF parameters from Slice
- add activation (to avoide overwriting when a new APS arrives)
- rename macro
