- Add macro for code changes.

The fix was confirmed as part of the specification.

 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

Implement option B for NAL unit header syntax.
NOTE: Neither the JVET-O0129-v2 or the JVET-O2001-vEJVET-O2001-vE documents specify a nal unit type NAL_UNIT_VPS, and this nal unit type is required. In this implementation NAL_UNIT_VPS is defined to be 25.

 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.

- CVS to start with GDR

- 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.

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

Implementation for JVET_N0100, proposal 1, allow signaling information about long-term reference picture POC LSB in reference picture list syntax structure.
