JVET-O0236 Removal of a parsing dependency

 The following fixes has been made:

   - Removed prefixes like 'i' for new variables

   - Adding braces also for if-clauses with a single statement

   - Removed some trailing spaces

   - Changed variable precedingDRAP in Picture from int to bool

 Implementation of the Dependent RAP indication SEI message. Pictures are marked as DRAP pictures using the encoder config parameter DRAPPeriod, which sets DRAP pictures periodically. Conformance checks are performed at the decoder side to verify that the DRAP pictures follow the constraints in the VVC specification.

 Added back the TMVPModeId config parameter. \n m_PPSTemporalMVPEnabledIdc is now set based on both TMVPModeId and PPSorSliceMode.

- add option to completely disable
- add iparameter to software manual
