JVET-P0983/P0391: remove sps maximum sbt size flag: add configurable parameter to use 64 size SBT in encoder RDO

JVET-N0867: Added check to confirm that the GOP size and picture order fullfils the configured DetlaTimes. If not DeltaTimes in BP and picture Timing are not used.

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

Update cfg file for rasterscan slice

 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.

- catch std::bad_alloc explicitly
- remove catch-all handler

 Deriving values for m_PPSDepQuantEnabledIdc, m_PPSSixMinusMaxNumMergeCandPlus1, m_PPSFiveMinusMaxNumSubblockMergeCandPlus1 and m_PPSMaxNumMergeCandMinusMaxNumTriangleCandPlus1 in EncAppCfg.cpp when these parameters are to be signaled in PPS.

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